Thank you for your tips. I think I will change the tables and use some
minimal date instead of a null value to represent a constraint that is
valid all the time. An additional advantage of this approach is that I
can then make sure that the time intervals (I not only have a start
date, but also an

I've got a DELETE query that takes ~2 seconds to process
The reasoning is simple -- its doing referential checks, to make sure
that I'm not deleting a valid fkey , as several tables fkey on that
one.
The issue i'm running into is obvious: this should not take 2
seconds. anything that

You look there:

Dear Hubert,

1) "statement-level" and "row-level" straight from PostgreSQL:

Statement-level triggers follow simple visibility
rules: none of the changes made by a statement are visible to

For small and moderate size databases, I find that the simplest way to
estimate the database size is to do:
du -ks /var/lib/postgresql/data
...create a new database, restore a backup of the database in whose
size you're interested in
du -ks /var/lib/postgresql/data
Compare the first and second

The old way was to use du or similar. Recent versions (I believe =8.1,
but check the release notes to be sure) provide several useful functions
for this:
