pg_wrapper(7)
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 specifed 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.
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.
