There is not, but you could try patching the backend to set the
KEEPALIVE option on the TCP socket --- see StreamConnection() in
src/backend/libpq/pqcomm.c.

If that helps, I think it'd be reasonable to accept the patch as
an #ifdef'd chunk of code with a config.h variable to control it.
I'm a little hesitant to just drop it in unconditionally --- I don't
know whether KEEPALIVE is supported by all platforms...
