The code is here:
https://github.com/gsstark/retropg
The build script is called "makeall" and it applies patches from the
"old-postgres-fixes" directory though some of the smarts are in the
script because it knows about how to run older version of the
configure script and it tries to fix up the ecpg parser duplcate
tokens separately. It saves a diff after applying the patches and
other fixups into the "net-diffs" directory but I've never checked if
those diffs would work cleanly on their own.
