Trigger based solution where same trig can be used for any number of
tables by changing the parameter.
Will throw one of 2 exceptions on failure to use sequence for the
insert.
Many thanks,
This seems to be the simplest solution,

Thanks for this hint, I'll try to do this. Is there any change you could send
me your 02:00 AM script so that i use something *I know* is already working?
Perhaps off the mailing list, since maybe not everyone will enjoy code on
their mail.
Thanks.

I'd like to clarify that this will not be a full solution, since it will
not allow update of the table unless nextval has been used in the same

It's not a full solution anyway since it prevents any kind of update
on the table due to check constraints firing even if target field not
updated.
Well, we can extend the check within the trigger:
if (coalesce old.a=new.a -- Update
OR
new.a = currval(tg_argv[0] -- Insert
) then
unsubscribe

Hello everyone,
I'm trying to change the SYSID in pg_control (at least I think that is

doing that?
The back story, for those interested:

You'd have to modify
