Jan & Herouth,
I've been using this for some time but lately lots of data is going
into the system (hope this means more revenue as well ;-)
My point: when attempting to do a SELECT the table lock blocks even
this activity. Is this a bleeding lock? Shouldn't a simple SELECT
succeed? I dunno...but this is problematic as users are looking for
info while the data entry person is doing her thing...ouch.
Another bit of whining: in my PROGRESS dbs the user gets a NOTICE
when a table is LOCKED and his/her SELECT is on hold:
`tablename is in use by doofus on term/1a11...press CTRL-C or Wait'
Is there a way to implement this with pg?
Cheers,
Tom
