       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.
