Some relations with LZ4 used as the toast compression methods have been left around in the main regression test suite to stress pg_upgrade, but pg_dump, that includes tests much more picky in terms of output generated, had no actual coverage with this feature. Similarly to collations, tests only working with LZ4 are tracked with an additional flag, and this uses TestLib::check_pg_config() to check if the build supports LZ4 or not. This stresses more scenarios with tables, materialized views and pg_dump --no-toast-compression.
