If the SELECT command does not return any results, how do I

If anyone is interested, here is my solution to my problem, which I hope
will be obsolete when the issues with the FDO PostGIS provider are
fixed. I have also successfully tested this setup out with foreign key
constraints in the primary table only --- the secondary tables just use
primary key

Hi Anton,
Have you considered using PostGIS? (http://postgis.refractions.net). It
pg_start_backup will flush old transactions, thus you have full DB backup.
Unless you want them archived, no need to keep them

There are built-in types in PG for handling IP addresses - are they any

Triggers only apply to the exact table they're declared on, not
to child tables.
It does seem like there might be some use-case for applying a trigger to
child
I would have called the Entity table the parent table and not the child
table as the Account table inherits from Entity. Therefore it appears that
the trigger only works on the table where the actual row was added/belongs
to.
It would be great if triggers on the parent table would work for any
