No Devrim, I mean which can be the best form to setup replication between master and slave ... and when master goes down, if I put data on slave how can I update master node.
You don't need a replication system there. Use an SAN :) Here is the schema: +-------+ +-------+ |Master | |Slave | | | | | |Node | |Node | +-------+ +-------+ | | -------------------------- | | +-------------- | | | SAN or NAS | | | +-------------+You will install just operating system,PostgreSQL binaries and Cluster tools to both Master and Slave nodes. All $PGDATA will reside in the storage.
If master node goes down, Slave node will mount $PGDATA and continue working. When master node is up, slave will umount $PGDATA, stop its postmaster and will trigger master node and start its postmaster so that data will not be corrupted.
