Hi @list,
is it possible to disallow "set work_mem to ..." for regular
(non-superuser) users?
Background: a shared database server with multiple users.

We have discussed it and might offer that ability some day, but
currently there is no way to do that. There are so many ways to mess
things up with a bad query that we are unclear if restricting work_mem
is really helpful.

Preventing people from setting an appropriate work_mem might well create
more denial-of-service problems than it prevents.
