According to the INSTALL document which came with
the distribution (possibly the following remark has
been removed in recent versions?), for RedHat Linux:

----------------------------------------------------
In RedHat Linux edit file /etc/inittab to add the
following as a single line:

pg:2345:respawn:/bin/su - postgres -c
  "/usr/local/pgsql/bin/postmaster
   -D/usr/local/pgsql/data >>
   /usr/local/pgsql/server.log 2>&1 </dev/null"
----------------------------------------------------

When the postmaster dies, init will automatically
respawn it, much the same as getty, or xdm, etc.
Now, since init will be starting the postmaster,
the /etc/rc.d/init.d script should be removed and
the links to it in /etc/rc.d/rc[whatever].d should
also be removed (or you could just not run this
service using linuxconf using the control service
activity option). And, of course, the switches in
the inittab entry above should be adjusted accordingly
to the appropriate site's settings.

That should ease the symptom but the problem still
remains. We run an e-commerce type web-based
application backed by PostgreSQL 6.5 around the clock.
I haven't seen a postmaster die since 6.4.0. Is there
any indication as to what is causing the postmaster to
die?

Hope the above helps,
