Self-contained installation in a user's directory

Hello,

I am sorry I wasn't attentive enough when this issue was discussed a few
months back. Now I can't find the right keywords to get to it in the
archives.

I need to automate the procedure of getting a fresh postgresql source,
building and installing everything that it needs to run within a user's
home directory. The user is not supposed to have root privileges, and he
is not supposed to be DBMS and even UNIX-literate. The client processes
will run locally by a web server (no external TCP/IP connections will be
needed) and each of these will take care about starting the postmaster
if it is not running for some reason. Also, I would like to avoid having
a special postgres user on the system. This kind of installation is
mainly intended to support search and retrieval and will require little
or no update at all.

As far as I can see now, it is enough to substitute "postgres" with a
user name of choice. I did not find relevant options in configure. Could
someone please point me to the right place or indicate what other
problems I may need to solve?

Thank you,

Gene
