Any reason why a database would not get dumped by pg_dumpall?
Always run pg_dumpall as the superuser.
I do a nightly dump and have checked several days so far and the database is
missing in all so far. :-(
The only thing, for that DB, that got backed up was the database, but not a
single table. So far from what I see other DBs were restored ok (At least
the ones I have checked so far).
