Thread: pgsql: Fix cross-version compatibility checks of pg_verify_checksums

Fix cross-version compatibility checks of pg_verify_checksums

pg_verify_checksums performs a read of the control file, and the data it
fetches should be from a data folder compatible with the major version
of Postgres the binary has been compiled with, but we never actually
checked that compatibility.
