6568cef, that introduced the option, had an inconsistent behavior when it comes to configuration tables set up by pg_extension_config_dump, as the data of all configuration tables would included in a dump even for extensions not listed by a set of --extension switches. The contents dumped changed depending on the schema where an extension was installed when an extension was not listed. For example, an extension installed under the public schema would have its configuration data not dumped even when not listed with --extension, which was inconsistent with the case of an extension installed on a non-public schema, where the configuration would be dumped. Per discussion with Noah, we have settled down to the simple rule of dumping configuration data of an extension if it is listed in --extension (default is unchanged and backward-compatible, to dump everything on sight if there are no extensions directly listed). This avoids some weird cases where the dumps depended on a --schema for one. More tests are added to cover the gap, where we cross-check more behaviors depending on --schema when an extension is not listed.
