Re: ERROR: found xmin from before relfrozenxid

Hi All,
Apparently the issue appeared again in the same database but on different
table . In the last time dumping and restoring the table helped. However, I
dont understand why another table hit the bug if it was fixed in 9.6.9
while my db version is 9.6.10.

Any idea ?
