libpg 12+ working branch

[clux]

need to link libpgport and libpgcommon since libpg12

manually compiling in two extra pg libraries in the stable image on this branch:

• libpgcommon is found in src/common
• libpgport is found in src/port

and also using the link flags from an ancient pr: https://github.com/sgrif/pq-sys/pull/28/files for sgrif/pq-sys#27 but that's been ignored for 2 years...

lol this does totally work when adding in libpgport, libpgcommon and using goldranks fix

Note to self; tried the other potential fix branch on pq-sys with the following diff:

does not work. needs the explicit static link dependencies.
