pg_verify_checksums

A server utility for verifying checksums in PostgreSQL 11
This entry relates to a PostgreSQL feature which is deprecated and may be desupported in future releases.

pg_verify_checksums is a server utility which verifies data page checksums in a PostgreSQL 11 cluster.

pg_verify_checksums was added in PostgreSQL 11  and was replaced in PostgreSQL 12 by the more versatile pg_checksums.

Although data page checksums were introduced in PostgreSQL 9.3, previously no practical method existed for proactively verifying an entire database cluster. pg_verify_checksums provides a means of doing this. Note that it requires that the server is shut down cleanly.
