The OP claimed to be using PHP 5.1.2, which does have a call to
PQunescapeBytea(), although it also has the old code you're seeing
and a HAVE_PQUNESCAPEBYTEA macro that determines which to use.

Interesting that the command line php and the Apache module behave
differently.  I wonder if ldd would show the php executable and
libphp5.so linked against different versions of libpq; that would
add weight to Tom's suggestion that an old libpq might be responsible.
