NAME

       pg_wrapper - wrapper for PostgreSQL client commands

SYNOPSIS

       client-program [--cluster version/cluster] [...]

       (client-program: psql, createdb, dropuser, and all other client programs installed in
       /usr/lib/postgresql/version/bin).

DESCRIPTION

       This program is run only as a link to names which correspond to PostgreSQL programs in
       /usr/lib/postgresql/version/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:

       1.  explicit specification with the --cluster option

       2.  explicit specification with the PGCLUSTER environment variable

       3.  matching entry in ~/.postgresqlrc (see postgresqlrc(5)), if that file exists

       4.  matching entry in /etc/postgresql-common/user_clusters (see user_clusters(5)), if that
           file exists

       5.  If only one local cluster exists, that one will be selected.

       6.  If several local clusters exist, the one listening on the default port 5432 will be
           selected.

       If none of these rules match, pg_wrapper aborts with an error.

OPTIONS

       --cluster version/cluster
           cluster is either the name of a local cluster, or takes the form host:port for a
           remote cluster. If port is left empty (i. e. you just specify host:), it defaults to
           5432.

ENVIRONMENT

       PGCLUSTER
           If $PGCLUSTER is set, its value (of the form version/cluster) specifies the desired
           cluster, similar to the --cluster option. However, if --cluster is specified, it
           overrides the value of $PGCLUSTER.

       PG_CLUSTER_CONF_ROOT
           This specifies an alternative base directory for cluster configurations. This is
           usually /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.

FILES

       /etc/postgresql-common/user_clusters
           stores the default cluster and database for users and groups as set by the
           administrators.

       $HOME/.postgresqlrc
           stores defaults set by the user himself.
