Then as a first cut for modules, could we add CREATE MODULE
syntax which adds an entry to pg_extension like CREATE EXTENSION
does? And also add a new column to pg_extension to distinguish
modules from extensions.

The three-part path name resolution for functions would remain the
same, nothing would need to change there because of modules.

Would that be an acceptable direction to go?
