Have you had experience setting up and working with database replication?

Yes, I have experience configuring and working with database replication, particularly with PostgreSQL and MySQL. Replication allows creating copies of a database to improve fault tolerance and scalability. I usually set up asynchronous replication, where the primary server (master) sends changes to replicas (slaves).

Setting up replication in PostgreSQL involves changing parameters in postgresql.conf and pg_hba.conf, as well as starting the slave process with a connection to the master. This helps distribute read load and ensures data backup.
