Dennis,
Thanks for your reply.
No, the OLD server are no longer available (decommissioned) - the new
servers are definitely better h\w.
I do not have any queries to EXPLAIN ANALYZE as they are built by the
application and I am not allowed to enable logging on for that server - so
where do I go
Hello all,
Old servers that housed 7.4 performed better than 8.1.4 version...are there
any MAJOR performance hits with this version???
I set the postgresql.conf setting to equal that of 7.4 and queries still run
SLOW on 8.1.4...
I have perform maintenance tonight on the 8.1.4 server - any
No, I didn't UPGRADE it but that's what I inherited :( ...not sure of the
code page stuff because I am not the one who did the upgrade...I'm not sure
I know ENOUGH about POSTGRESQL to mess around with the codepage...
Yes, I use vacuum analyze...
Yes, I used the postgresql.conf of 7.4 and tried
How do I know if there is BLOATING??? I just ran vacuum verbose;
Yes, autovacuum is on.

Hello all,
I am a bit confused...I have a database which was performing very POORLY
selecting from a view (posted earlier) on one server but extremely fast on
another server...
I just backed up the database from the FAST server and loaded to the SLOW
server and it ran just as fast as it
to the
fast database? --- I am new, how do I know the size of the database (OS file
size ??))...is there an sp_helpdb equivalent command??
My EXPLAINS are under a previous thread:
Query is taking 5 HOURS to Complete on 8.1 version

taking over 5 hours to complete...can I use \timing??? I don't get any time
when using the \timing option...
Thanks...Marsha
