user_clusters - File linking users to PostgreSQL clusters
This file maps users against the database clusters to which they will
connect by default. However, every user can override these settings in
When scanning this file, the first matching line will be used. It is a
good idea to provide a default explicitly, with a final line where both
user and group are set to *.
If there is no default, the implicit default is to connect to the
cluster whose postmaster is listening on port 5432 and to the database
matching the user’s login name.
Comments are introduced by the character #. Comments may follow data
on a line; the first comment character terminates the data. Leading
whitespace and blank lines are ignored.
Each uncommented, non-blank line must describe a user, group or the
default (where both user and group are set to *).
Fields must be given in the following order, separated by white space:
USER The login id of the Unix user to whom this line applies. The
wildcard character * means any user.
GROUP The group name of the Unix group to which this line applies. The
wildcard character * means any group.
The major PostgreSQL version of the cluster to connect to.
The name of a cluster to connect to. A remote cluster is
specified with host:port. If port is empty, it defaults to 5432.
Within the cluster, the database to which the user will connect
by default if he does not specify a database on the command
line. If this is *, the default database will be the one named
by the user’s login id.
Since the first matching line is used, the default line must come last.
