KrahoDB: multi-master replication

KrahoDB provides a multi-master replication for PostgreSQL. It is
designed on the top of logical replication, providing bidirectional
replication, as well as row filtering. It takes advantage of
publish-subscribe model and implements two main features: origin
filtering and row filtering. The origin filtering allows data does not
return to its origin. It is the basis of bidirectional replication.
Row filtering can select which data will be sent to subscribers. It
means that some subscribers could receive partial data.

KrahoDB is a PostgreSQL fork. This is the first public release. We
provide versions based on PostgreSQL 10, 11, and 12. It is licensed
under PostgreSQL license.
