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.
