Regarding parallel running of 9.1 and 9.2beta2

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?
