Hi. The following Todo item seems already resolved in pg15. https://wiki.postgresql.org/wiki/Todo#Triggers
> Tighten trigger permission checks > > - Security leak with trigger functions? > <http://archives.postgresql.org/pgsql-hackers/2006-12/msg00564.php> > > But it seems to not appear in the pg15 release notes. (I searched for the keywords "trigger" and "function").
