The problem was that the new psql was linking to an older version of
libpq.so (one that doesn't export get_progname()). As best I can tell
that would have had to be a 7.3 libpq.so, which means there is something
wrong here because the 7.3 libpq should have had a different minor
number that would prevent the dynamic linker from accepting it as a
substitute. What platform are you using?
