FWIW, that doesn't seem especially canonical from here. In particular, pg_dump will not normally result in any examination at all of indexes on user-defined tables --- it'll just be doing seqscans of the tables proper. You could hope for reasonably complete coverage of the system catalogs along with user tables, but missing out user indexes seems like a pretty big gap. The actual solution for this as of v11 is pg_verify_checksums (renamed to just pg_checksums for v12). I don't think there's any really convincing answer before v11. regards, tom lane
