I can't reproduce the problem either...

pg_encoding_to_char is in common.c from backend/utils/mb/.  The way that
psql gets holds of it is that in a MULTIBYTE build, common.c is built
and included in libpq (interfaces/libpq), and then psql links with
libpq.

Two likely theories are

(1) for some reason your link is picking up a different copy of libpq
than the one present in interfaces/libpq (link search path issue); or

(2) you've got a compiled copy of libpq that was compiled without
MULTIBYTE support, and hasn't gotten updated since you reconfigured
with MULTIBYTE support.

The latter would arguably be a failure to maintain proper dependencies.
I'm not sure if Peter is trying to force a global rebuild when you
reconfigure or not; maybe you're expected to do "make clean" when you
alter configuration choices.

Anyway, seems like the first thing to look at is whether
interfaces/libpq/libpq.a (or .so or .sl) contains pg_encoding_to_char
(use nm(1) to check).  If not, is there a common.o file in that
directory?
