Subject: unlooged tables

Hi,

Where in pg_catalog I can find, if the table was created as "unlogged" (or not)?
As in: create unlogged table t1(c1 int);
I can't seem to find this info in pg_catalog tables/views.

Tried psql with -E to describe (\d) unlogged table, but it was not helpful.

Regards,
Igor Neyman

Sorry for the noise.
As soon as previous message was sent I found it:

relpersistence column in pg_class ("u" for unlogged tables, "p" - for "normal" tables)

SELECT relpersistence FROM pg_class WHERE relname = 't1';

'u' is unlogged, 'p' is persistent, 't' is temporary.
