If they are permanent tables used for temporary storage then making them

Interesting, yes, I was wondering why PG didn't make temp tables
unlogged by default.
Then, I guess, the docs[0] have to mention it. Especially due to the
error condition. Right?

Well, the fact that temporary and unlogged cannot be simultaneously
specified *is* documented:
CREATE [ [ GLOBAL | LOCAL ] { TEMPORARY | TEMP } | UNLOGGED ] TABLE [ IF
NOT EXISTS ] table_name
But it would probably be worth adding a note under the description of
temporary tables that they are, in fact, unlogged.
Cheers,
Steve
