Hi all,
is there a way (also strange) to define a trigger on a system table (for
example on pg_class)?
I tried but I got (as expected) a permission denied message...

Hi,
You can use one procedure(function in Postgres) but you have to use 26
triggers.
Every trigger can call this one procedure to record the information you
want.

I've run in to a small problem when writing a trigger.
For simplicities sake lets say that I have 2 tables – 'bookings' and

Use a rule instead. 7.2 will reject an attempt to insert into a view
