pg_encoding relies on libpq to supply the pg_valid_server_encoding()
subroutine, but that subroutine is only compiled into libpq in a
MULTIBYTE build.  I speculate that your executable was picking up
a non-MULTIBYTE libpq shared library from someplace.  Check ldconfig
and all that stuff...

FWIW, both multibyte and non-multibyte builds are working OK for me
in current sources.
