Hi people,

I'm involved in several projects nowadays, and that makes me the need to install several postgresql versions.

My actual problem is, how can I install postgresql-8.3.1 and postgresql-8.3.4 on ubuntu (linux).

Anyone knows how can I do it?
Thanks!

You shouldn't need to install both because there won't be any functionality differences between the two minor releases.

You can install two major versions (like 8.3 and 8.4) on ubuntu because it puts the config and data files in separate folders by default (/etc/postgres/8.4/...).

But to do this, you'll only be able to install 1 thru synaptic, and the other you'll need to install using 1-click installer or compile your own.

Obviously you'll need to put them on different ports.

Hi, thank you for your answer
I only need to use one at a time, so think that I can use the same ports.

I am using: the following commands to install postgres:
1) $ tar xvzf postgresql-8.3.5.tar.gz
2) $ cd postgresql-8.3.5/
3) $ ./configure --with-pam
4) $ make
5) $ sudo make install

And it installs postgres into folder: /usr/local/pgsql.

How can I decide were to put them?
Thanks once more
