If my memory serves, unlogged tables are not nuked when PostgeSQL is stopped by a planned shutdown (not by crash or by "pg_ctl -m i stop"). If PostgreSQL works so, incremental backup should be able to recover unlogged tables as well, at least people would expect so IMO. -- Tatsuo Ishii SRA OSS, Inc.
