Subject: [PATCH] Drop long deprecated function register_tstz_w_secs()

Deprecated in commit b263fbf274f9085a1bddca018ed8a50d37023fc7 on
2010-01-13. The deprecation warning was first released in version 2.2.2.

The function used to register an alternate type caster for TIMESTAMP
WITH TIME ZONE to deal with historical time zones with seconds in the
UTC offset. These are now correctly handled by the default type caster,
so currently the function doesn't do anything.
