Under RedHat, ~postgres is /var/lib/pgsql, not the _obvious_ /home/postgres.
No, there needs to be a particular place for such commands. And /usr/sbin is
THE FSSTND-mandated place (now called the FHS -- www.pathname.com/fhs) Quoting
FHS 2.0:
---------------------------------------
Filesystem Hierarchy Standard

4.7 /usr/sbin : Non-essential standard system binaries

This directory contains any non-essential binaries used exclusively by the system
administrator. System administration programs that are required for system
repair, system recovery, mounting /usr, or other essential functions should be
placed in /sbin instead.

Typically, /usr/sbin contains networking daemons, any non-essential administration t
ools, and binaries for non-critical server programs. These server programs are used
when entering the System V states known as "run level 2" (multi-user state)
and "run level 3" (networked state) or the BSD state known as "multi-user
mode". At this point the system is making services available to users (e.g.,
printer support) and to other hosts (e.g., NFS exports).

-----------------------
Now, looking into my /usr/sbin, I find two owners -- root, and uucp. That's
right -- most of the uucp stuff that is not executed except during daemon-time
(uucico, uuxqt, and friends) is in /usr/sbin. Making the database service
available in "multi-user" mode is a good job for a binary in /usr/sbin.

Now, this is only if PostgreSQL is being installed in an FHS-compliant manner.
Otherwise, make a /usr/local/pgsql/sbin.

It might be useful to provide an FHS-compliant configure option (hey, it would
make it easier for us packagers ;-)).

Whoa. Hold on. Having '.' in PATH is a _major_ security hole. It is almost
never a good idea for '.' to be on the PATH. If you want to go the ~postgres
route, make a bin or sbin dir under ~postgres, and add '~postgres/bin' to PATH
in .profile.

IMHO.
