Metadata from NEW and OLD constructs?
Greetings,
I was wondering if it's possible to get any of the metadata from the NEW
and OLD constructs in a trigger or view rule? Specifically, I'd like to
get the column name or identifier anywhere the new record differs from
the old record (i.e. NEW.column_X <> OLD.column_X). Any advice would be
greatly appreciated.
Thanks,
JL

If your trigger is written in C, definitly. If the trigger is in
pl/pgsql, no. For other languages I don't know. which language are you
using?
Have a nice day,
