The Win32 equivalent is DllMain, which I believe only works when your a
dll. Although, from the WSAStartup docs:
"the WSAStartup function should not be called from the DllMain function
in a application DLL. This can potentially cause deadlocks."
That doesn't sound inviting. C++ static intializers would probably
work, if isolated in some small far away distant project file with an
ugly file name.
Outside of user-land work arounds, the real fix would be to have a libpq
library init and shutdown (shutdown only useful for those wanting to
free resources or re-init libpq differently). Not sure there's any
interest in this idea.
