Looks to me like the linker is trying to link against a pre-7.4 version
of libpq.so --- those are all symbols that got added in 7.4.  Probably
it is taking the existing installed version of libpq.so in preference to
the just-built one in the source tree.

Dunno what the clean solution to this under AIX is, but a brute force
answer is to go ahead and install the new libpq (gmake install in
src/interfaces/libpq) and then continue with building ecpg.
