Neither am I. This database was created before I was responsible for
this project, a few years ago - by someone who has left already (which
is a good thing, in his case).

There were 2 or 3 triggers on each refering/referencing table, of which
I assume they were generated by postgresql. I do recall that creating
foreign keys stopped working suddenly (maybe due to an update by our
sysadmin), after which we created the triggers by hand... The "we" here
usually not including me.

I would like to show some of those triggers, but due to the clutter
caused by all the foreign keys we created that way up til last year or
so, that's quite an ordeal... There are tables where the tabel
definition scrolls out of view rather rapidly...

I never liked the way this was solved by my predecessor, this seems a
good opportunity to fix it.
