It's OK for "path" variables (e.g. PQINCPATH, PQLIBPATH) to be empty
if the corresponding header/library is in a standard directory (i.e.
can be found without any -L/-I switches).
However, the actual "lib" variables (e.g. PQLIB) generally need a
value. The absence of one indicates that "configure" failed to link a
test program. This can be because the library isn't present, or
because the compiler isn't looking in the right directory, or because
the library has a dependency which configure hasn't allowed for.

How long ago was that?

As of a couple of weeks ago, configure no longer adds -I or -L
switches of its own accord. Without arguments, headers/libraries will
only be found if they are in a directory which the compiler/linker
You can force particular headers/libraries to be looked for in
particular directories using the --with-foo-includes= and
--with-foo-libs= switches, where foo is one of zlib, jpeg, tiff, png,
gd, tcltk, postgres, opengl, odbc, fftw, blas, lapack.
You can force directories to be searched for all headers/libraries
using the --with-includes= and --with-libs= switches.
