To my mind, the most straight-forward way of dealing

this is to remove the language from template1
altogether.
Thereafter, the db owner must explicitly add it back in
where required. So, the default would be no extension.
Well that is how it was prior to 9.0.
It does not now appear to be the case. When I drop the
test database and attempt to recreate it the plpgsql
extension is automatically added back in with postgres as
the owner. This was a new installation of 9.1 and I have
made no modifications to the templates whatsoever.

The language can still be removed from a particular database if the
administrator has security or performance concerns about making it
available.

Prior to version 9.0 plpgsql was included with the database but not
installed until the DBA requested it. Starting with 9.0 it was installed
by default. Basically went from opt-in to opt-out. You do not have to
touch template1, the language is already loaded. If you do not want that
behavior you have to remove it from template1 or any 'template' database
you choose to CREATE a new database from. In your case, the new database
you created inherited the language from template1 with the super user
privileges. To undo that, in that particular database, you need to DROP
the superuser version of the language(as the superuser) and then
recreate it as the database owner user to get it to run as that user.
For future use, assuming you do not want new databases to inherit the
superuser version of plpgsl, you need to DROP it from template1.
