This is an unusual one. The OS isn't handling things properly, and we
have to work around that. Can you get a Win32 user to test psql with
this patch to make sure it actually fixes the problem and behaves as
expected? If you want me to produce a psql binary, I can do that.
Thanks.

I'm the maintainer of sql.el in GNU Emacs. On both the Mac OS X
and the Windows/Cygwin platform we've had reports that psql run
under Emacs does not issue a prompt for commands.
I did a little research and it appears that the cause is that
pset.notty is being set to false because stdin/stdout are not
a tty (pgsql-server/src/bin/psql/startup.c). I'd like to
propose that an option be added to the psql command line to
override the detection of the tty and force the prompting for
commands on stdin.
I believe the attached patch should add the option -I to psql
and force the prompt to appear as if it were an interactive
session regardless of the state of stdin/stdout. I do not
have a configuration available to properly test this however.
Please be sure to include me in any replies since I do not
subscribe to this list. TIA.
