database - Postgresql: direct replication on demand -


i have 2 postgresql databases (on different servers): lets call them stable , unstable. stable read purposes only. time time the stable updated current unstable.

i improve update process. dumping file , restoring not possible more due size of database. found many replication tools designed master-slave configuration, not do, slave (stable) updated on demand. tools seem more complicated problem want them solve.

ideally, simple tool interface pg_replicate source target result in target db being exact clone of source , data being transfered directly between 2 database servers (they connected local network) without creating large temporary files. database size 50 gb , growing, transfering sql inserts might not suffice.

so, there tool it? or close?
