Title:
  /usr/bin/psql misinterprets cluster version in ~/.postgresqlrc

Status in “postgresql-common” package in Ubuntu:
  Triaged

Bug description:
  I've just upgraded a client from precise to trusty. As part of that
  upgrade, postgresql-client-9.1 was uninstalled and replaced with
  postgresql-client-9.3. This broke the psql client's access to
  databases that are listed in ~/.postgresqlrc as running version 9.1.
  If I run

  psql dbname

  I now get the following error:

  Error: /home/username/.postgresqlrc line 2: version 9.1 does not exist

  The relevant line of /home/username/.postgresqlrc looks like this:

  9.1                dbhost:5432      dbname

  This is correct according to the documentation: the postgresqlrc(5)
  man page describes the VERSION column as "The major PostgreSQL version
  *of the cluster to connect to*" (emphasis mine). Note also the comment
  in /usr/share/postgresql-common/pg_wrapper that says:

  # for psql we always want the latest version, as this is backwards compatible
  # to every major version that that we support

  Unfortunately the flow of control never reaches that point in the
  code; user_cluster_map() (in PgCommon.pm) calls version_exists(9.1)
  and throws an error because *on the client* there is only version 9.3.
  The check is erroneous since it assumes that the client and the server
  have the same versions of PostgreSQL installed.

  I could lie to the wrapper and claim that the database cluster runs
  version 9.3, were it not for the fact that /home/username is on a
  network share and the same file needs to work for both precise and
  trusty (and wheezy) clients.

  This report is about Ubuntu 14.04 LTS, with version 154 of postgresql-
  client-common. I haven't researched whether any other releases are
  affected.
