postgresql92: Various security fixes. Update to 9.2.4. (important)

postgresql was updated to version 9.2.4 (bnc#812525):

• CVE-2013-1899: Fix insecure parsing of server
  command-line switches. A connection request containing
  a database name that begins with "-" could be crafted
  to damage or destroy files within the server’s data
  directory, even if the request is eventually rejected.
• CVE-2013-1900: Reset OpenSSL randomness state in each
  postmaster child process. This avoids a scenario
  wherein random numbers generated by "contrib/pgcrypto"
  functions might be relatively easy for another database
  user to guess. The risk is only significant when the
  postmaster is configured with ssl = on but most
  connections don’t use SSL encryption.
• CVE-2013-1901: Make REPLICATION privilege checks test
  current user not authenticated user. An unprivileged
  database user could exploit this mistake to call
  pg_start_backup() or pg_stop_backup(), thus possibly
  interfering with creation of routine backups.
