=head1 NAME
pg_wrapper - wrapper for PostgreSQL client commands
=head1 SYNOPSIS
I<client-program> [B<--cluster> I<version>/I<cluster>] [...]
(I<client-program>: B<psql>, B<createdb>, B<dropuser>, and all other client
programs installed in C</usr/lib/postgresql/>I<version>C</bin>).
=head1 DESCRIPTION
This program is run only as a link to names which correspond to PostgreSQL
programs in C</usr/lib/postgresql/>I<version>C</bin>. It determines the
configured cluster and database for the user and calls the appropriate version
of the desired program to connect to that cluster and database, supplying any
specified options to that command.
The target cluster is selected by the following means, in descending order of
precedence:
=over
=item 1.
explicit specification with the B<--host> option
=item 2.
explicit specification with the B<--cluster> option
=item 3.
if the B<PGHOST> environment variable is set, no further cluster selection is
performed. The default PostgreSQL version and port number (from the command
line, the environment variable B<PGPORT>, or default 5432) will be used.
=item 4.
explicit specification with the B<PGCLUSTER> environment variable
=item 5.
matching entry in C<~/.postgresqlrc> (see L<postgresqlrc(5)>), if that
file exists
=item 6.
matching entry in C</etc/postgresql-common/user_clusters> (see
L<user_clusters(5)>), if that file exists
=item 7.
If only one local cluster exists, that one will be selected.
=item 8.
If several local clusters exist, the one listening on the default port 5432
will be selected.
=back
If none of these rules match, B<pg_wrapper> aborts with an error.
For B<psql>, B<pg_archivecleanup>, and B<pg_isready>, B<pg_wrapper> will always use the binary from
the newest PostgreSQL version installed, as these are downwards compatible.
=head1 OPTIONS
=over
=item B<--cluster> I<version>B</>I<cluster>
I<cluster> is either the name of a local cluster, or takes the form
I<host>:I<port> for a remote cluster. If I<port> is left empty (i. e. you just
specify I<host:>), it defaults to 5432.
=back
=head1 ENVIRONMENT
=over
=item B<PGCLUSTER>
If C<$PGCLUSTER> is set, its value (of the form I<version>/I<cluster>)
specifies the desired cluster, similar to the B<--cluster> option. However, if
B<--cluster> is specified, it overrides the value of C<$PGCLUSTER>.
=item B<PG_CLUSTER_CONF_ROOT>
This specifies an alternative base directory for cluster configurations. This
is usually C</etc/postgresql/>, but for testing/development purposes you can
change this to point to e. g. your home directory, so that you can use the
postgresql-common tools without root privileges.
=item B<PGSYSCONFDIR>
This is the location of PostgreSQL's and postgresql-common's global
configuration (e. g. C<pg_service.conf>, L<user_clusters(5)>). The default is
C</etc/postgresql-common/>.
=back
=head1 FILES
=over
=item C</etc/postgresql-common/user_clusters>
stores the default cluster and database for users and groups as set by
the administrators.
=item C<$HOME/.postgresqlrc>
stores defaults set by the user himself.
=back
=head1 SEE ALSO
L<user_clusters(5)>, L<postgresqlrc(5)>
