Hello.
I wanted to know what it would take to implement triggers on foreign tables.
It seems that statement-level triggers can work provided they are allowed in
the code.
Please find attached a simple POC patch that implement just that.
For row-level triggers, it seems more complicated. From what I understand,
OLD/NEW tuples are fetched from the heap using their ctid (except for BEFORE
INSERT triggers). How could this be adapted for foreign tables ?
