The natural way in AIX would be:
- Create libpq.so
- Create libpq.a by 'rm -f libpq.a; ar -rc libpq.a libpq.so'
- Install only libpq.a
For a static build on AIX, you have to specify all the libraries and
give the linker -bstatic and -bI:/lib/syscalls.exp

I have done that (see the attached patch) and it works fine.
I don't have the native AIX C compiler, so I could only test
it with gcc.
I have taken the liberty to modify the static link line
in Makefile.global.in to contain the LDAP libraries, I hope
that's appropriate.
