- 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)
