Turn the -i/--ignore-version options of pg_dump and pg_dumpall into no-ops:
the server version check is now always enforced. Relax the version check toallow a server that is of pg_dump's own major version but a later minorversion; this is the only case that -i was at all safe to use in.pg_restore already enforced only a very weak version check, so this isreally just a documentation change for it.Per discussion.
