It seems that triggers are not inherited, so to get the functionality I
want I'll have to create a trigger for each table. If anyone knows
another way, please let me know!
After you pointed me in the right direction, I was able to create a
trigger procedure which can be called from triggers on various tables
and will log the operation (including the affected table's oid and
name). The procedure is listed below. Thanks for the help!
create or replace function add_log_entry() returns TRIGGER as '
insert into audit_log(table_oid, table_name, id, operation) values
(TG_RELID, TG_RELNAME, NEW.id, TG_OP);
' language 'plpgsql';
