I have only a small remark about dynamicly loaded modules.
In the current state (in Cygwin) is postgres.exe manually linked as a
DLL, but with EXE suffix. So it creates an import library (with all
symbols exported = libpostgres.a) during the process of DLL creation and
all modules are linked with this library. I copied and modified the
process (which calls dlltool many times) very long ago (1998) from some
Cygwin docs about DLL creation.
I think it should be possible to use the same process in Mingw build
process for native PostgreSQL.

Agreed, but does Mingw's ld support exporting symbols directly from an
executable? Cygwin's ld does:

If so, then maybe it's time to remove the dlltool stuff and make Cygwin
and Mingw more like the other Unixes (e.g., gcc -shared).
