Hello all, I went through the documentation on replication. and am trying to understand the various options available. Does replication available in PostgreSQL always use WAL (i.e irrespective of whether it is synchronous/asynchronous, whether it is using archived logs or 'live' logs or streaming)?
I understand that we can use WALs in 3 modes 1) Use the archived WALs - results in the slave being significantly behind the master. This is set up using the archive_command 2) Use entire WAL segments 3) Use 'streaming' , i.e. use WAL files before they are complete - in this case the slave is almost uptodate If I set up a slave using the archived WAls and set hot_standby on in the slave, will I be able to read from the slave?
