Hi,
I am running PostgreSQL 9.1 currently and I want to run 9.2beta2
simultaneously with it.Is it possible?
Yes, You can have multiple PostgreSQL versions on same host.
I downloaded the 9.2beta2 sources,untared them and ran
./configure,make and make install without uninstalling 9.1.
./configure --prefix=<new location of PostgreSQL 9.2 beta2 binaries>
make
make install
<new location of PostgreSQL 9.2 beta2 binaries>/bin/initdb -D <new data directory location of 9.2beta2>
modify "Port" number in postgresql.conf file located under <new data directory location of 9.2beta2>
<new location of PostgreSQL 9.2 beta2 binaries>/bin/pg_ctl -D <new data directory location of 9.2beta2> start
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?
Suspecting for this error message is, binaries upgraded upto 9.2beta2 & PostgreSQL instance running with PostgreSQL 9.1 binaries and again you are trying to start instance with pg_ctl of 9.2beta2 binary.
