What exactly is in that TAR backup? Is that a tar/gzipped PG dump or a
file-system snapshot?
If the latter:
- did you halt the database while creating the snapshot or at least
force a checkpoint?
- is the version of PG that you're restoring to exactly the same (same
CPU type, same major/minor version of PG) as the one that the backup
is from?
I suspect that you restored a database with corrupt statistics and
that those only get found out once the corrupted statistics are
needed.
