<h2>
Synopsis
</h2>
<p class="indent" style="white-space:nowrap;">
<code>MS_PGSQL_PRIV_ROOT(DB, USER, [HOST], [PASSWORD], [ACTION_IF_FAILED],
[ACTION_IF_OK])</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
This macro checks wether the given PostgreSQL user has root privileges (can
create and drop databases) It is recommended to first call
MS_CHECK_PGSQL_DB, this makes it easier to locate the cause of error. The
macro MS_PROG_PGCLIENT is required by this one.
</p>
<p>
The variable $pgclient_root_call is set for later use in Makefiles, if
you'd like to make use of this, you must do
</p>
<pre>
AC_SUBST(pgclient_root_call)
</pre>
<p>
after having called MS_CHECK_PGSQL_PRIV_ROOT. You can then do something
like the following in your Makefile.am:
</p>
<pre>
@pgclient_root_call@ -f file.sql
</pre>
<p>
If you want the user to set the data, you should support something like
these configure options:
</p>
<pre>
AC_ARG_WITH(pgsql-host,
[ --with-pgsql-host=HOST server is running on HOST @<:@local socket@:>@],
[pg_host=$withval], [pg_host=])
AC_ARG_WITH(pgsql-db,
[ --with-pgsql-db=DBNAME use database DBNAME @<:@test@:>@],
[pg_db=$withval], [pg_db=test])
AC_ARG_WITH(pgsql-root-user,
[ --with-pgsql-root-user=USER use user USER, must have root (all) privileges @<:@postgres@:>@],
[pg_root_user=$withval], [pg_root_user=postgres])
AC_ARG_WITH(pgsql-password,
[ --with-pgsql-password=PASSWORD use password PASSWORD @<:@none@:>@],
[pg_password=$withval], [pg_password=""])
</pre>
<p>
You can then call the macro like this:
</p>
<pre>
MS_CHECK_PGSQL_PRIV_ROOT([$pg_db], [$pg_root_user], [$pg_host], [$pg_password], [AC_MSG_ERROR([We need root privileges on database!])])
</pre>
