The The node where a publication is defined is referred to as publisher. It is an open-source value because its code is available to everyone. Logical replication is a method of replicating data objects and their changes, based upon their replication identity (usually a primary key). Deploying a single PostgreSQL instance on Docker is fairly easy, but deploying a replication cluster requires a bit more work.

PostGIS is a spatial database extender for PostgreSQL object-relational database. In order to be able to copy the initial data, the role used for the replication connection must have the SELECT privilege on a published table. The plugin transforms the changes read from WAL to the logical replication protocol and filters the data according to the publication specification.
