Oh, I see the problem. Observe this comment in the libpgtcl sources:
Another headache is that Ousterhout keeps changing the Tcl I/O interfaces.
libpgtcl currently claims to work with Tcl 7.5, 7.6, and 8.0, and each of
'em is different. Worse, the Tcl_File type went away in 8.0, which means
there is no longer any platform-independent way of waiting for file ready.
So we now have to use a Unix-specific interface. Grumble.
Tcl_CreateFileHandler() and Tcl_DeleteFileHandler() are the
Unix-specific routines that this comment is talking about.
In other words, it's just not gonna work on Windows, unless you want to
downgrade to Tcl 7.* or add the appropriate Windows-specific interface
code. Sorry about that ... but I think most of the fault lies over in
the Tcl camp ...
Anyway, if you do feel like adding the necessary code, a patch would be
BTW: it's possible, nay likely, that the I/O situation has changed yet
again in newer Tcls. Perhaps there is once again a platform-independent
I/O interface, in which case fixing the problem with respect to 8.3
would make a lot more sense than adding an 8.0 solution.
I haven't time to work on this at the moment, but surely there are
some Tcl'ers out there who care.
