On top of what John Pierce says in the thread, I would very strongly
urge you not to do this. It makes troubleshooting on failure
notoriously hard. Use the mechanisms the start-up files do, I
suggest.
That said, see section 18 of the manual -- in particular, 18.1.3 in
the 9.3 manual ("Other ways to set parameters"). I recommend against
all that on the basis of some somewhat painful experience, but you can
do it that way.
If you're determined to do it, I _strongly_ suggest using several
different postgres.conf files and then only using the config_file
parameter to control this. At least then you can look at what the
settings were when you have a crashed or otherwise troublesome system.
Best,
A
