pgsql2shp(1) PostGIS pgsql2shp(1)
NAME
pgsql2shp - postgis to shapefile dumper
SYNTAX
pgsql2shp [options] database [schema.]table
pgsql2shp [options] database query
DESCRIPTION
The pgsql2shp table dumper connects directly to the database and con-
verts a table (possibly created by user query) into a shape file. It is
compatible with all versions of PostGIS.
Version: 1.1.5 (2006/10/06)
USAGE
The <database> is the name of the database to connect to.
The <table> is the (optionally schema-qualified) table to read spatial
data from. Alternatively, you can specify a QUERY whose result will be
written into the shapefile.
OPTIONS
The commandline options are:
-f <filename>
Write the output to a particular filename.
-h <host>
The database host to connect to.
-p <port>
The port to connect to on the database host.
-P <password>
The password to use when connecting to the database.
-u <user>
The username to use when connecting to the database.
-g <geometry column>
In the case of tables with multiple geometry columns, the geome-
try column to use when writing the shape file.
-b Use a binary cursor. When used on pre-1.0.0 PostGIS versions
this will reduce the likelihood of coordinate drift due to con-
version to and from WKT format. Coordinate drifts will not occur
with PostGIS 1.0.0 and newer versions. It will be slightly
faster, but might fail if any NON-gemetry column lacks a cast to
text.
-r Raw mode. Do not drop the gid field, or escape column names.
-d For backward compatibility: write a 3-dimensional shape file
when dumping from old (pre-1.0.0) postgis databases (the default
is to write a 2-dimensional shape file in that case). Starting
from postgis-1.0.0+, dimensions are fully encoded.
-k Keep idendifiers case (don't uppercase field names).
-? Display version and usage information.
INSTALLATION
To compile the program from source, simply run "make" in the source
directory. Then copy the binary in your shell search path (or wherever
you like). This text is also available as a man page in the ../doc/man/
directory, ready for copying it into the manual search path on unixoid
systems.
EXAMPLES
An example session using the dumper to create shape file from a
database might look like this:
# pgsql2shp -f myfile -p 5555 my_db roads_table
