+ On Windows, you need to register an event source
+ and its library with the operating system in order
+ to make use of the <systemitem>eventlog</systemitem> option for
+ <varname>log_destination</>.
+ See <xref linkend="event-log-registration"> for details.

* This part is not strictly correct - you don't *need* to do that, it
just makes things look nicer, no?
* Also, what is the use for set_eventlog_parameters()? It's just a
string variable, it shuold work without it.
* We these days avoid #ifdef'ing gucs just because they are not on
that platform - so the list is consistent. The guc should be available
on non-windows platforms as well.
* The guc also needs to go in postgresql.conf.sample
* We never build in unicode mode, so all those checks are unnecessary.
* Are we really allowed to call MessageBox in DlLRegisterService?
Won't that break badly in cases like silent installs?
Attached is an updated patch, which doesn't work yet. I believe the
changes to the backend are correct, but probably some of the cleanups
and changes in the dll are incorrect, because I seem to be unable to
register either the default or a custom handler so far.
