This is awfull way of doing configuration. Why should different
installation share anything, in one file? Running
/usr/bin/pg_ctl -C /etc/postgres.isp1.conf start
seems much more maintainable. And /etc/postgres.isp1.conf can specify
that the data files are in /bigdisk/data/isp1x or wherever you
please.

One file does not add possibility of multiple versions of postgresql
on same box, it merely makes it harder.

That does not necessarily mean the idea is broken. Tom's main
objection (IIRC) was that he needs to be able to have multiple
postgresqls on one machine. That can easily be achieved, either by
specifying datadirectory in the configuration file, or even defaulting
to the same directory where the .conf file is stored when no
datadirectory option is used.
