The main thing is that it adjusts shared_buffers down until the server
will start without exceeding the OS limits. It also sets some locale
parameters within the database.

The errors are probably in /var/lib/pgsql/9.0/pgstartup.log

Most of the time the problem is either:

a) shared_buffers and the other memory parameters are set too high for
the OS settings.
b) There is already an instance running, or some file left behind from
an earlier instance, that is blocking startup of the new server.
c) A file is missing, corrupted, or has the wrong permissions

All of the common cases identify themselves clearly in the log file.
