I just discovered two bugs and attached a patch to correct them :
- the jdbc escaped scalar function dayofweek should return values
between 1 and 7 (1 for sunday) unlike the backend "extract dow" function
- the literal escaped values for date/time/timestamp were not explicitly
casted and causing some problems : for example
extract( dow from '2005-01-17 12:00:00')
generate an error, but the following is accepted
extract( dow from TIMESTAMP '2005-01-17 12:00:00')

Applied. Thanks for the report & patch.
While testing this patch I noticed we have existing date-related
regression failures (not related to the patch) against 7.2.x:

Is it worth fixing this?

This appears to be an oddity of the +1300 timezone. Both of the following
work:
select '2000-02-07 15:00:00.120000+13'::timestamptz;
select '2000-02-07 15:00:00.120000+1200'::timestamptz;
We potentially could hack around this on the driver, but it looks to me
like a server problem, so I'd leave it alone based on the number of people
it affects (7.2 & +1300).

I believe this is a server bug, not JDBC's fault. The timestamp code
rejected +1300 as an invalid timezone until not too long ago. It is
valid though...
