Hi Wei Shan, I've been through this and this is simple. I've been using my PostgreSQL 9.4 database using psql 9.2 for months and all went fine. To workaround it, you can compile PostgreSQL client 9.2.4 in another directory, and run the binary that you compiled in that directory. For example if you make new PostgreSQL client compile with prefix=/opt/postgresql-9.2.4 You can run the psql like this: /opt/postgresql-9.2.4/bin/psql <your server, maybe signserver> To help yourself, search in the web for: - how to compile postgresql in a specific directory - how to edit the PATH environment in RedHat linux or Debian or centos or your choice Hope this helps.
