Thanks, I've heard that, but in this case won't exactly fit my needs...
..First, I'm working on a PostgreSQL 8.1.4 modification, and it
would be really difficult to add all the changes I've made to the
...Second, I need to do all this form the backend (Postgres
Source Code). I can't use any User or Administrator defined
functions or sometime like that.
Well, maybe I didn't make myself clear, this is what I need to do:
I need to know the values of some fields (columns) from the last
inserted tuple. The problem is that I need to do this in the moment
I'm inserting a new one (all from the backend code) and compare
the values between the new one (N.O) and the all ready inserted (A.R.I),
and if the N.O fits some properties (according to the A.R.I) it must
be decided if it has to be finally inserted or not.
I think there's not to much difficulty on that, but until now I haven't
found how to access that information. I can reach the HeapTuple
structure according the A.R.I tuple, but I don't know how to access
the information (values for its attributes) stored on it.

8.2 has (INSERT/UPDATE/DELETE) ... RETURNING. Perhaps you could use
the 8.2 series instead :)
