       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 ~/.postgresqlrc.

       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 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.
