Thread: pgsql: Support unlogged tables.
Support unlogged tables. The contents of an unlogged table are WAL-logged; thus, they are not available on standby servers and are truncated whenever the database system enters recovery. Indexes on unlogged tables are also unlogged. Unlogged GiST indexes are not currently supported.

Sigh. s/are/aren't/, as Devrim just pointed out to me off-list. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
