Обсуждение: reorg - pg_reorg: Use one of not-null unique keys to identify rows when

Log Message:
-----------
Use one of not-null unique keys to identify rows when the target table doesn't
have a primary key. Some of users want to use not-null unique keys rather than
primary keys because postgres doesn't support REINDEX PRIMARY KEY CONCURRENTLY.

- Support 9.1dev.
- Improve Makefile to use PGXS automatically.
