Also i must add, that the database on the production system
was never dumped/reloaded since the creation of the system.
The production 7.2.1 pgsql db was created and loaded on 2002-04-20,
from a 7.1.3 pgsql on our previous Solaris box (which we replaced
with a new linux one).
The production pgsql is started/stopped only during
system shutdowns/boots.
We had some unexpected system failures due to some
Linux/MotherBoard/BIOS problems.
(I was too enthusiastic about pgsql and its stability
that i was overconfident about our database's state
after these failures).
BTW, could that be the cause of the problem??
The problem is that i didnt realize the problem until yesterday.
The only thing i am sure, is that some of the triggers lost
one both linux'es are present on the FreeBSD system,
which was populated on Oct 22, and had NO deletion activity
at all.
I plan to make a huge map of all my tables, and configure
all the pairs of tables with inter-referential integrity constraints,
pg_dump --schema-only, see which triggers are missing
and then create them by hand.
Has anyone got a better idea??
After recreating the missing triggers should i upgrade
to 7.2.3??
Thanx.
