Brian Cloutier 62e7bdbdd6 Switch from pg_worker_list.conf file to pg_dist_node metadata table. ... Related to #786 This change adds the `pg_dist_node` table that contains the information about the workers in the cluster, replacing the previously used `pg_worker_list.conf` file (or the one specified with `citus.worker_list_file`). Upon update, `pg_worker_list.conf` file is read and `pg_dist_node` table is populated with the file's content. After that, `pg_worker_list.conf` file is renamed to `pg_worker_list.conf.obsolete` For adding and removing nodes, the change also includes two new UDFs: `master_add_node` and `master_remove_node`, which require superuser permissions. 'citus.worker_list_file' guc is kept for update purposes but not used after the update is finished.		2016-10-05 13:01:35 +03:00
