Allows passing wal2json's add-tables and filter-tables options via pgstream config (YAML and env vars). These filter at the source-side decode level, preventing wal2json from generating JSON for excluded tables — dramatically reducing CPU and network overhead. Config: source.postgres.replication.plugin.add_tables: "public.*" source.postgres.replication.plugin.filter_tables: "pipelines.*,private.*" Env vars: PGSTREAM_POSTGRES_REPLICATION_PLUGIN_ADD_TABLES PGSTREAM_POSTGRES_REPLICATION_PLUGIN_FILTER_TABLES
