BUG #5714: TZ pattern error on to_timestamp

"Alexander Loechel" <Alexander.Loechel@unibw.de> writes:

After an update on my ubuntu system of postgres 8.4.4 to 8.4.5 the
to_timestamp methode produces different results.

in a CREAT View statement I have following methode call:
to_timestamp(dbtimestamp, 'YYYY/MM/DD HH24:MI:SS TZ') AS "timestamp"<<

Where dbtimestamp is a String coming from a CMS.

before migration it produces normal timestamps
after migration I get following Message:

"ERROR: TZ/tz format patterns are not supported in to_date"

Testing shows that that example fails in every Postgres release back to
7.1. The spelling of the error message varies a bit, but they all agree
that a TZ format spec isn't supported.

I don't know what changed in your installation, but it wasn't this.

Any reason why Pg can't parse TZ?
perhaps it should be also listed in
http://www.postgresql.org/docs/current/interactive/functions-formatting.html
doc, that you can't use TZ (and some other patterns too)?

Nobody's bothered to do the work ...

Nobody's bothered to do the work for that, either.
