Hi Jim,
Thanks for having a look at my patch, but please don't top post on

It doesn't tab complete the AT TIME ZONE operator itself, just the
timezone name after it, so this sholud work:
# SELECT now() AT TIME ZONE <tab><tab>
or
# SELECT now() AT TIME ZONE am<tab>
However, looking more closely at the grammar, the word AT only occurs in
AT TIME ZONE, so we could complete the operator itself as well. Updated
patch attatched.

Subject: [PATCH v2] psql: tab completion for AT TIME ZONE
Commit 7fa3db367986160dee2b2b0bbfb61e1a51d486fd added support for
completing time zone names, use that after the AT TIME ZONE operator.
Also complete the operator itself, since it's the only thing in the
grammar starting with AT.
