Hey postgresql gurus,
I was just wondering, what kind of frontend do you recommend in 'bills
(windows...)' environment?
Is it better to use a tool like Qt from trolltech or is it better to use
something like Omnis or Access???
What are you opinions
best regards,

Is it possible to do variable substitution with explicit locks in plpgsql?
Something along the lines of

EXECUTE ''LOCK TABLE ''

Hi all -
I'm having a strange problem creating a rule on a view.
I've done this with no problem in other databases... I'm wondering if
somehow there was something omitted or some other type of prolem with
the database creation. Or, I could have no idea what I'm talking about.
Any guesses?

The first query is able to use the index on nr_proponente, because the
condition involves that column directly, the second query is not,
because the index only contains the values of nt_proponente, not results
of trunc(..)/
Try replacing that condition with something like
pa.nr_proponente B

1st. The function wich substitute the trunc() function

Not in general --- only for an indexscan lookup.

Never. That's what
