Actually, first it should be *corrected*.  It should say "... defined
before the POSTMASTER is started".  Or even more directly, "... supplied
in the postmaster's environment variable set".

As is, it can reasonably be read that you just have to define the variable
in your own environment before starting a psql session (which starts a
backend of course).

The critical distinction that people aren't making is between their
client environment and the postmaster/backend environment, and the
existing text doesn't seem to help them.
