Yes we can of course. I modify the mc file.

Question: Doesn't MC also generate a .bin-file? IIRC, the .RC file is
just a reference to the .BIN?

Correct, the file was missing in my post !

If not, then it's an easy go - I suggest we put both the .RC and the .MC
file in, so things will still build fully from mingw. If not, I don't
know what the deal is about binary files - could we stuff a
pre-generated .BIN file in CVS? [I know cvs can, but is that acceptable
in postgresql?]

write_eventlog() cannot do this, since the postmaster will run as a
non-administrator, and thus not have permissions under that key.
The installation program should normally do this.

I would suggest implementing the DllRegisterServer() and
DllUnRegisterServer() entrypoint in a small C file that is compiled into
the DLL. That way, a user can just run "regsvr32 pgevent.dll" (or
whatever it's called).

If everybody is OK, I will make this extension during the week.

It's ok for me
