Umm, Ctrl-C doesn't quit less, it aborts the current command. So if
it's doing a search or you've hit "F" (follow) or any number of other
things then the only way out is to press Ctrl-C. You have to press "q"
to quit less like you say.

The system() function blocks -INT and -QUIT, as does the shell when you
run a program, so why not?

The point is, less is still running but psql it pulling the keystrokes
from under it... When you finally quit less it does restore the
settings, but now readline doesn't expect that as it's changed them
again...
Have a nice day,
