Skip foreign tablespaces when running pg_checksums/pg_verify_checksums Attempting to use pg_checksums (pg_verify_checksums in 11) on a data folder which includes tablespace paths used across multiple major versions would cause pg_checksums to scan all directories present in pg_tblspc, and not only marked with TABLESPACE_VERSION_DIRECTORY. This could lead to failures when for example running sanity checks on an upgraded instance with --check. Even worse, it was possible to rewrite on-disk pages with --enable for a cluster potentially online.
This commit makes pg_checksums skip any directories not named TABLESPACE_VERSION_DIRECTORY, similarly to what is done for base backups.
