Thanks, I didn't know about that feature, that solves half of my problem.

For configuring the authn matching yes, the use case is multitenancy.
But for some other variables that we didn't implement yet, this could
be useful even without multitenancy.
One thing I mentioned in the previous email is the client id
validation. A practical use case of that would be restricting which
oauth clients can login to which database. I can't use a SUSET
variable with a check restricting it to ALTER DATABASE, because
database level variables are not yet available during the oauth
validator callback. I could use a login event trigger, but that seems
like a bad hack to me.
