Ok folks, I have successfully installed Postgresql 7.3.1. in my Debian Potato running on a P133. Actually, it was easier than what I expected. All the necessary steps for the installation are outlined in the INSTALL file.
There is one question I have for which I could not find an answer in this file though, what do I do to make Postgresql sever to start at boot time while at the same time kill in it at shutdown time?

Thanks in advance.
