Deployment of replication to PostgreSQL service operates as follows:
Service Alpha on the Extractor, extracts the information from the MySQL binary log into THL.
Service Alpha on the Applier reads the information from the remote replicator as THL, and applies that to PostgreSQL using a standard JDBC driver by constructing PostgreSQL compatible SQL to insert, update and delete the target data.
The two replication services can operate on the same machine, (See Section 5.3, “Deploying Multiple Replicators on a Single Host”) or they can be installed on two different machines.
