Is it possible to perform the table level PITR in postgresql version 9.6 or 10, if yes could u plz assist .If no ,then is there any facilities/utilities provided in upgraded postgresql versions like 11 or 12
No, WAL interleaves all data in the cluster, PITR simply stops WAL replay. PITR will not produce a corrupted database cluster. You have to PITR the whole thing then pull out the table from the restored version.
