As the result of a recent exp-run for postgresql 9.3, several ports
failed to build as a result. Most could likely be fixed by updating the
port to a later available version. Until that happens, set the maximum
version of pgsql to 9.2 for these ports.
* pg_rman (1.23) : version 1.27 is available
* pg_statsinfo (2.4.1) : version 2.5.0 available, works on pgsql 9.3
* pgpool-II (3.1.6) : version 3.4 available, works on pgsql 9.3
* pgpool-II30 (3.0.4)
