Corrupted table?

[Sinloud]

Hi everybody

Looks like i somehow corrupted history_uint table, i get this error when i try to do something with it
ERROR: could not access status of transaction 650650
DETAIL: Could not open file "pg_xact/0000": No such file or directory.

Is there a way to fix this and if not, how safe it is to truncate this table?

Hi!
Try to remove index and recreate it.
Also, it may happen if you've got some serious filesystem-level or RAM problems.
Ofc, you have to make a backup before doing anything on the database.
