In general, mingw built modules should load just fine in msvc built
postgres. AFAIK, that's how PostGIS does it for 8.3 (though I know Mark
is working on getting MSVC build support for them). Debugging may be a
bit harder (since they use different kinds of debug symbols - postgres
uses Windows style and mingw uses mingw style), but it should certainly
load.
What trouble exactly are you seeing?
Basically, "Procedure not found", even though it is there. Also note
that the same R.dll is being used from the MinGW Postgres installation
(where plr loads successfully) and the MSVC Postgres.
