- Vacuum Space Map - Maintain a map of recently-expired rows

    This allows vacuum to target specific pages for possible free
    space without requiring a sequential scan.

- Deferrable unique constraint

- Probably trivially easy would be to add an index to pg_listener

- Tougher but better would be to have pg_listener be an in-memory
  structure rather than being physically represented as a table

- MERGE / UPSERT

- Config file "#includes" for postgresql.conf, pg_hba.conf

- Some better ability to terminate backends 

- Automatically updatable views (per SQL 99)
