It sounds like your superuser account has a default search_path that
includes the schema this function is in, but your drupal_user account
has a different default search_path that doesn't.  You could put the
extension in a different schema, or change drupal_user's search_path.

Ah, scratch that (-ENOCAFFEINE).  What seems more likely on re-reading
this is that drupal_user lacks USAGE privilege on whatever schema contains
the uuid-ossp functions.  Depending on which PG version you're using,
I believe that unreadable schemas in your search_path are silently
skipped.  You could confirm that by trying to call the function using
an explicitly schema-qualified function name, and seeing if you get
a permissions error about the schema.
