So, if you do psql -c "..."
with both of those \watch instructions, do either one hang? (I am now
guessing "no")

I know that perl is using a special library to "remote control psql" (like
a pseudo terminal, I guess).
[I had to abort some of the perl testing in Windows because that perl
library didn't work with my psql in Windows]

Next, can you detect which process is hanging? (is it perl, the library,
psql, ?).

I would be curious now about the details of your perl install, and your
perl libraries...
