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 CW/usr/lib/postgresql/versionCW/bin).
DESCRIPTION
This program is run only as a link to names which correspond to PostgreSQL
programs in CW/usr/lib/postgresql/versionCW/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 \s-1PGCLUSTER\s0 environment variable
"3."
matching entry in CW~/.postgresqlrc (see postgresqlrc(5)), if that
file exists
"4."
matching entry in CW/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
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
"\s-1PGCLUSTER\s0"
If CW$PGCLUSTER is set, its value (of the form version/cluster)
specifies the desired cluster, similar to the --cluster option. However, if
--cluster is specified, it overrides the value of CW$PGCLUSTER.
FILES
stores the default cluster and database for users and groups as set by
the administrators.
stores defaults set by the user himself.
