If you are setteing PGCLIENTENCODING before starting up postmaster, or
you are setting client_encoding in postgresql.conf, then that is a
known bug. Currently the fix is in current, but not in the 7.3 stable
tree to avoid the backward compatibilty with prior releases. This is
due to the fact that libpq calls pg_client_encoding() function which
is only available in 7.3 or later if you apply the fix.

If you need patches for 7.3.1, I could provie it for you, though they
would lose the backward compatibilty with prior releases.
