allow postgis_restore.pl to work on directory-style backups (-Fd)

[wrog]

This allows doing hard-restore/upgrade from a directory-style (-Fd) backups as well as the usual postgres-custom backup (-Fc). (You have -f which unnecessarily restricts backup to being an ordinary file but pg_restore deals just fine with directories. Also, you really do want to test -r)

This is literally a one-character change (though you could also fix $manifest 4 lines earlier to remove trailing slashes from $dumpfile).
