Hi,
I have a query of the form select min(tab1.a) over(partition by tab1.b
tab2.a tab1.c) from .
in db2. What will be the corresponding query for postgres. Does Postgres
have a function which provides the same functionality??
Regards,
Vinita Bansal
Thank you for the feedback. I am considering just centralizing pk
generation to the HQ. Basically, every so often, the branch will connect
back to HQ to get back a block of pk for each table. This way, performance
impact is limited and maintainence is simple.
thanks.

Generally, the stuff in pgcontrib, when installed, only affect a single

loaded on demand. For databases not configured, they won't even see
them.
As for security risks, this is the only real issue. The code is not in

There is a theory that text is faster than varchar, because postgresql
doesn't have to check text.
Hi Michael,
Well, I dumped the database from two different versions of Postgres
(on different machines), using both pg_dump 8.0.0beta2 and pg_dump 7.4.2
(which correspond to the respective server versions). I only restored
on the 8.0.0beta machine, though. Would that make a difference?
