Subject: 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.
