Thread: Install two different versions of postgres which should run in parallel

Hi all,

I need to have two different vesions of postgres running in parallel on
different ports. Does anyone knows how to install two different versions
of postgres (7.4.5 and 8.2.4) on the same computer? I am using Linux
operating system.

Any information would greatly be appreciated.

You can install from source and provide the --prefix argument to the
configure command.

If you run Debian or Ubuntu you can do this with the package system.

  apt-get install postgresql-8.2 postgresql-7.4

The two versions are automatically installed to run on different ports.
Look at the docs and manpages for the postgresql-common package to see
how it works.

If you can't do that, you can install a different version from source in
a different directory tree; then have its postmaster run on a different
port.  Specify the port number when connecting so as to get to the
postmaster you want.

I didn't succeed installing the two versions of postgres.
For installing I am running the "configure" script as follows:

./configure --prefix=/usr/local/pgsql-7.4.5 --with-java --with-pgport=6947

Although I specify a different port than the default one, the postgres it is installed with the
default port. The port must be specified also in another configuration files?

On what grounds do you conclude that?  I use --with-pgport every day.
It works fine.
