Folks,
I noticed a little unimplemented feature which I suspect a lot of
people would find useful, namely the ability to "freeze" certain
settings for a role.
Example: We'd like to create a role called read_only, with eponymous
capability. At the moment, we can't do what's below, but I'd like to
be able to make it possible. First, we'd issue the following, which
doesn't work yet:
ALTER ROLE read_only SET transaction_isolation read_only;
Then, there's one way via DCL (Data Control Language)
REVOKE SET transaction_isolation FROM read_only;
Another would be via DDL:
ALTER ROLE read_only FREEZE transaction_isolation;
I'd think of the reverse of each of these as GRANT and ALTER ... THAW,
respectively.
Is anyone else interested in such a feature? If so, is it more
DCL-ish, or more DDL-ish?
Cheers,
David.
