Hmmm, running it more interactively I see what was probably the hang
when run from the scheduler:

---------------------------
psql.exe - Application Error
---------------------------
The instruction at "0x7c8396d0" referenced memory at "0x00000014". The
memory could not be "read".
Click on OK to terminate the program
Click on CANCEL to debug the program
---------------------------
OK Cancel
---------------------------

(if that got fired off under the scheduler it would appear to hang as
there would be no display to display it on, and no way to hit OK or
Cancel).

Unfortunately gdb is giving a somewhat useless backtrace (yes, this is a
debug build):

Visual Studio can't do much better, but that's to be expected because it
can't understand the mingw debug symbols.

:-(
