We are having 2 database servers (Debian 8.3) with postgresql. 1st server having postgresql 8.4 and 2nd server is having postgresql 9.4.

Would it be possible to setup bucardo between this 2 database servers?

Please let me know. Any hint will be really appreciated.

Yes. Bucardo can replicate between different versions of Postgres. Bucardo 5.6 will work from v8.1 to at least v12.

In fact Bucardo is used sometimes to upgrade PostgreSQL version without downtime.
