Hi!

I have to migrate application from Delphi/MSSQL to Kylix/<free_rdbms>.
One of things used in this app is INSERTED/DELETED tables in triggers.
It's something like NEW and OLD records, but may contain multiple rows.

My questions are:
How difficult would it be to implement such a feature in PostgreSQL?
What impact would it have on pgsql performance/memory reqiurements?
Would it be useful for somebody else?

Thanks in advance,
Tom
