Oh, so you're able to select from your table but select
returns 0 tuples?
Ok, what exactly vacuum verbose says about your table with
1800 tuples (vacuum' message asis, please).
I saw something like this when pg_variables was corrupted
and table' tuples weren't visible because of next_xid
was too small but I need in vacuum message to know
is it that case or not.
