dev-db/postgresql: Security Bump

Security update fixes issues:

1. CVE-2015-5288: The crypt() function included with the optional
pgCrypto extension could be exploited to read a few additional bytes
of memory. No working exploit for this issue has been developed.

2. CVE-2015-5289: json or jsonb input values constructed from
arbitrary user input can crash the PostgreSQL server and cause a
denial of service.

Also added note for new installations that re-sourcing /etc/profile is
reuiqred to pick up environment changes, like MANPATH so man can find
pages installed in non-standard locations.
