Allow a pager to be used by the \watch command. This works but isn't very useful with traditional pagers like "less", so use a different environment variable. The popular open source tool "pspg" (also by Pavel) knows how to display the output if you set PSQL_WATCH_PAGER="pspg --stream". To make \watch react quickly when the user quits the pager or presses ^C, and also to increase the accuracy of its timing and decrease the rate of useless context switches, change the main loop of the \watch command to use sigwait() rather than a sleeping/polling loop, on Unix. Supported on Unix only for now (like pspg).
