That is way too old. Upgrade to 14.20

Run the pg_checksums program to get a handle on the extent of the corruption

Database backups are affected by corrupted data.
I assume you are not using a good backup system then. pgBackRest, for
example, will not only check for corrupted pages during the backup, but
report on it and allow the backup to proceed.
