And the term "volatile" has well-understood connotations that are
analagous to those in DB2 in the C language and various descendants.

I'm not sure "UNLOGGED" is perfect... If "TEMPORARY" weren't already

Other possibilities include TRANSIENT, EPHEMERAL, TRANSIENT, TENUOUS.
FLASH would be an amusing choice. "PostgreSQL 9.1, now with support for
