Subject: [PATCH] Fix documentation of to_char/to_timestamp TZ, tz, OF
formatting patterns.
These are only supported in to_char, not in the other direction, but the
documentation failed to mention that. Also, describe TZ/tz as printing the
time zone "abbreviation", not "name", because what they print is elsewhere
referred to that way. Per bug #14558.
