v7.0.2: can't use 'EXTRACT(EPOCH FROM'
I'm running postgres 7.0.3 on one machine and 7.1.2 on another. I tried
running the exact SQL sample from the user manual for date time
functions:
SELECT EXTRACT(EPOCH FROM TIMESTAMP '2001-02-16 20:38:40');
This example won't run on the v7.0.3 and I get teh following error:
ERROR: parser: parse error at or near "epoch"
However, the same SQL sample runs on v7.1.2. Am I doing something wrong
here? Is this a known bug?

No, it simply didn't exist back then.

For versions prior to 7.1 (and for current versions also), try
SELECT EXTRACT('epoch' FROM TIMESTAMP '2001-02-16 20:38:40');
(note the single quotes around "epoch"). 7.1.x also allows the
non-quoted form you gave as an example.
