Through Docker Compose, the guide demonstrates setting up a main database and a replica, creating tables, populating data, and configuring the replication. Key considerations include the WAL settings and the limitations of logical replication, such as the necessity for identical schemas between the primary and replica databases. The guide also covers using PGAdmin for database management and offers tips for managing schema changes.
