Hi All, Here I announce the pgcat project: Enhanced postgresql logical replication.
The built-in logicial replication has below shortages: * only support base table as replication target * do not filter any origin, which will cause bi-directional dead loop * could not do table name mapping * no conflict resolution pgcat makes below enhancements: * supports any table type as replication target e.g. view, fdw, partitioned table, citus distributed table * only replicates local changes so that you could make bi-directional replication, e.g. replicates data between two datacenter * table name mapping * optional lww (last-writer-win) conflict resolution * save replication progress in table, so that it would be logged when subscriber failovers, it would retain the progress. In contrast, the built-in logical replication of pg saves the progress in non-logged file. Please check https://github.com/kingluo/pgcat for more detail. Thanks! Regards, Jinhua Luo
