The patch looks OK at first glance, and I can confirm that it works as intended. I can imagine this functionality being useful, e.g. to watch pg_stat_activity or similar tables. But a big part of why watch(1) is nice is that the output is overwritten rather than scrolling. When it's scrolling, it's (a) difficult to notice that something has changed, and (b) harder to compare values, especially when the interval is short. For these reasons, I can imagine using "watch -n2 psql -c …", but not \watch in its present form. (Of course, I doubt anyone would be enthused about a proposal to link ncurses into psql, but that's another matter.) Maybe you should call it \repeat or something. I'm sure people would get around to using \watch that way eventually. :-) -- Abhijit -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
