We have seen problems like this when multibyte-enabled programs (such as
pg_encoding) got linked against a non-multibyte-enabled libpq. The
routines pg_char_to_encoding and pg_encoding_to_char are in libpq ...
but only if it's been compiled multibyte.
I speculate that there is a non-multibyte libpq in /usr/local/pgsql/lib,
and for some reason your linker is seizing on that copy to use, rather
than the one in ../../../src/interfaces/libpq (which presumably is
multibyte enabled). Since you didn't mention your platform I have no
idea what might be done to fix this, short of clearing out
/usr/local/pgsql/lib while you build.
In the long run it might be a good idea if non-multibyte libpq still
contained (stub versions of) these routines ...
