new features.

  * Add -T, --tabs option to make pg_format use tabs instead of space
    characters.  When this option is used spaces number is set to 1
    whatever is the value set to -s, --spaces.

  * Allow output to override source file.

  * Add option -g, --nogrouping and CGI corresponding checkbox. By
    default pgFormatter groups all statements when they are in a
    transaction:
    
        BEGIN;
        INSERT INTO foo VALUES (1, 'text 1');
        INSERT INTO foo VALUES (2, 'text 2');
        ...
        COMMIT;
    
    By disabling grouping of statement pgFormatter will always add an extra
    newline characters between statements just like outside a transaction:
    
        BEGIN;

        INSERT INTO foo VALUES (1, 'text 1');

        INSERT INTO foo VALUES (2, 'text 2');
        ...

        COMMIT;
    
    This might add readability to not DML transactions.

    line.
  * Add 'Wrap after' option to CGI in the indentation section to
    support the -W | --wrap_atfer command line option in CGI mode.
  * Add -w | --wrap-limit command line option to be able to to wrap
    queries at a certain length. This option is not available in CGI
    mode.
  * Allow uploaded file content-type to be application/octet-stream.
  * Allow a single $ sign in object name.
  * Major optimization of function detection, speed difference is 10
    time faster.

    functions.
  * Add detection of code separator after DO keyword if it starts
    with a dollar sign.
  * Add new option -t | --format-type to try another formatting type
    for some statements. At this stage it will just use a multi-line
    format in POLICY and PUBLICATION statements. It also introduce
    newline in parameter function list.
  * Add formatting of CREATE POLICY statements.
  * Add information about (Neo)vim plugin and Visual Studio use of
    pgFormatter to format PLPGSQL and SQL code.

        SELECT a, b, c, d FROM t_1, t_2, t3 WHERE a = 10 AND b = 10;
    
    is formatted into:
    
        SELECT a, b, c, d
        FROM t_1, t_2, t3
        WHERE a = 10
            AND b = 10;
    
    Note this formatting doesn't fits well with sub queries in list.

Febuary 28 2018 - v3.0

This major release fixes some issues reported by users during the
last six months and adds several new features.

  * Add colorization of comments.
  * Add detection and colorization of user defined function in the SQL
    code. Until now only PostgreSQL internal function was highlighted.
  * Add new option -B | --comma-break and in CGI the checkbox
    "New-line after comma (insert)" to force a newline after each
    comma in INSERT statements, columns and values parts.
  * Add command line option: -F | --format to be able to change the
    output format in CLI mode. At now there is two possible format,
    text the default or html. More format can be added in the future.
  * Add support to all psql meta commands up to v1O.

There is also some improvement in SQL code formatting. Here is the
complete list of changes:

  - Add information on how to customize CSS in CGI to change the HTML
    style.
  - Update documentation and add a pointer to the Node.js wrapper
    written by Gajus Kuizinas.
  - Remove program extention from $self->{program_name} used as title
    of the CGI interface.
  - Remove html_highlight_code() method to apply HTML formatting style
    at token level instead of full SQL content like before. You just
    have to call the $object->beautify() method, the HTML formatting
    will be called internally if you have set the out format to HTML
    with the call to $object->format('html'). This call is now done
    internally by pg_format when it is called with the -F html option
    or in CGI mode. This compatibility break justify a change of the
    major version number.
    
    Note that this breaks backward compatibility if you are using your
    own custom scripts. With a complete upgrade and the use of the
    pg_format script and libraries everything should work as before.
    
  - Improve the CGI interface where the footer bar overlaps.
  - The CGI library also support a new internal parameter/option
    $self->{ 'colorize' } used to disable HTML output formatting
    to avoid applying colorization to error messages returned by the
    Perl package pgFormatter::CGI.pm
  - Improve documentation of the Perl Package.
  - Add detection of user defined function in the SQL code. Until now
    only PostgreSQL known function was highlighted. Thanks to Gajus
    Kuizinas for the feature request.
  - Add option -B | --comma-break to documentation.
  - Add regression test to CASE formating.
  - Fix poorly formatted output when using CASE statements within
    function params. Thanks to Kale Davis for the report.
  - Add new option -B | --comma-break and in CGI the checkbox
    "New-line after comma (insert)" to force a newline after each
    comma in INSERT statements, columns and values parts. Thanks
    to Troy Johnson for the feature request.
  - Add sample of insert statement to test new -B option
  - Improve formatting of multiple join.
  - Add new regression test on JOIN formatting.
  - Add command line option: -F | --format to be able to change the
    output format in CLI mode. At now there is two possible format,
    text the default or html. More format can be added in the future.
    This allow embedded call to pg_format from any other program and
    send a more sophisticated format than simple text to be able to
    detect keywords, function and punctuation in that program.
  - Add Hubert depesz Lubaczewski to the main authors list.
  - Add simple regression test on psql meta command.
  - Add support to all psql meta commands, thanks to Tobias Bussmann
    the patch.
  - Remove regexp pragma for negative look backward (use re '/aa';)
    it is no more necessary since html_highlight_code() method is
    gone. The requirement of minimal Perl version 5.14 should no
    more needed but it is preserved for now. The demo isite is working
    well on Perl 5.10.


September 02 2017 - v2.1

This minor release fixes several issues reported by users since four
months.  This release also adds some improvements in code formatting.

  - Add support to new psql meta-command from v10.
  - Remove new line before ORDER BY with string_agg and group_concat
    function call. Thanks to Huy Pham for the report.
  - Fix CREATE TYPE format. Thanks to Fabian Zeindl for the report.
  - Fix fix full outer join formatting. Thanks to Jakob Egger for the
    report.
  - Fix indentation in CTE. Thanks to Jakob Egger for the report.
  - Add two command line option to defined where comma must appears
    in a parameter list:
    
     -b | --comma-start: in a parameters list, start with a comma (see -e)
     -e | --comma-end  : in a parameters list, end with a comma (default)
    
    The CGI interface adds a new checkbox to force comma at beginning.
    Default is lines end with a comma. Thanks to fnwiya for the
    feature request.
  - Fix use of uninitialized value in pattern match. Thanks to Gajus
    Kuizinas for the report.
  - Fix missing space after a function name especially in ALTER
    FUNCTION calls.
  - Add sample to regression test on CTE, CREATE TYPE and dynamic code
    formatting.
  - Prevent dynamic code formatting. By default pgFormatter takes all
    code between single quote as string constant and do not perform
    any formatting on this code. It is common to use a string as
    code separator to avoid doubling single quote in dynamic code
    generation, in this case pgFormatter can fail to auto detect
    the code separator. By default it will search for any string after
    the EXECUTE keyword starting with dollar sign. If it can not auto
    detect your code separator you can use the command line option -S
    or --separator to set the code separator that must be used. Thanks
    to Alvaro Herrera for the report.
  - Fix undetected case of BEGIN keyword when lowercase.
  - Add test case for GRANT and DISTINCT FROM formatting.
  - Remove newline between DISTINCT and FROM. Thanks to Sebastian
    Albert for the report.
  - Fix GRANT formatting. Thanks to Vesa Karjalainen for the report.
  - Make it possible to run pg_format via symlink. For example, if
    pgFormatter is in /opt/pgFormatter and there is a symlink like
    /usr/local/bin/pg_format -> /opt/pgFormatter/pg_format
    then previous version wouldn't work when called via symlink, as
    it would search for libs in /usr/local/bin/lib/, and not in
    /opt/pgFormatter/lib.
  - Move COALESCE from SQL keyword to SQL function to prevent new line
    after comma in the parameters.

the best free tool to rewrite and beautify any SQL and PLPGSQL code. This
release also fixes several issues and adds lot of improvements in code
formatting.

    - Add PLPGSQL beautifier.
    - Fix case sensitivity of plpgsql keywords when using the -u command line
      option. Thanks to Hubert Depesz Lubaczewski for the report.
    - Add regression tests script regress_test.pl, more test files and expected
      results.
    - Do not append newline before a concatenation operator.
    - Fix unitialized variable issue and remove newline in insert statement
      after a close parenthesis.
    - Remove comment before HTML beautifier and restore them after to prevent
      beautifying keywords in comments.
    - Improve formatting of UPDATE and DELETE statement.
    - Improve all DDL statements formatting.
    - Only format functions when name is followed by an open parenthesis.

January 23 2017 - v1.6

This release fixes several issues and adds lot of improvements in
query formatting.

Command line option --placeholder or -p has been added to be able
to set regex to find code that must not be formatted. For example,
in query like:

	SELECT * FROM projects WHERE projectnumber
		IN <<internalprojects>> AND username = <<loginname>>;

you may want pgFormatter to not interpret << and >> as bit-shift
keywords and modify your code snippsets. You can use a Perl regular
expression to instruct pgFormatter to keep some part of the query
untouched. For example:

        pg_format samples/ex9.sql -p '<<(?:.*)?>>'

will not format the bit-shift like operators.

Here is the complete list of changes:

  - Improve SQL formatting by reducing space with parenthesis and
    cast with ::.
  - Add two sample file to test placeholder feature and WITH query.
  - Fix missing newline after INNER JOIN. Thanks to Julien Rouhaud
    for the report.
  - Fix whitespace placed in between the E and the quote character.
    Thanks to clijunky for the report.
  - Fix lots of operators reported on issue #22. Thanks to Laurenz
    Albe for the report and list of missing operators.
  - Fix version number in lib/pgFormatter library files.
  - Add -p | --placeholder command line option to prevent pgFormatter
    to replace some part of the SQL queries. Thanks to jhelberg for
    the feature request.
  - Fix bad formatting with anonymized values in queries. Thanks to
    Pilat66 for the report.

October 17 2015 - v1.5

This release fixes several issues and adds support to new keywords added in
PostgreSQL 9.5. There's also a major code rewrite by Hubert depesz Lubaczewski,
pg_format works as previously - handles both CGI and CLI interface, but you
can get directly to whatever functionality you want by using pgFormatter::*
modules.

New beautified keywords are: BERNOULLI, CUBE, GROUPING SETS, SKIP LOCKED,
LOGGED, POLICY, ROLLUP, TABLESAMPLE. And new functions are: jsonb_pretty,
jsonb_set, pg_last_committed_xact, pg_xact_commit_timestamp.

There is also a useful hint added to documentation to be able to format
you SQL code from vi by adding a simple line to .vimrc. This hint is taken
from David Fetter's blog : http://people.planetpostgresql.org/dfetter/index.php?/archives/78-Formatting!.html
