Hi, I am running PostgreSQL 9.1 currently and I want to run 9.2beta2 simultaneously with it.Is it possible? I downloaded the 9.2beta2 sources,untared them and ran ./configure,make and make install without uninstalling 9.1. Now,when I am running pg_ctl start,I am getting the following error: pg_ctl start server starting gitc@ubuntu:~/Downloads$ FATAL: database files are incompatible with server DETAIL: The data directory was initialized by PostgreSQL version 9.1, which is not compatible with this version 9.2beta2. Please help me.What should I be doing to recover from this error and get back to 9.1?
