Hi hackers!
From time to time I want to collect some stats from locks, activity
and other stat views into one table from different time points. In
this case the \watch psql command is very handy. However, it's not
currently possible to specify the number of times a query is
performed.
Also, if we do not provide a timespan, 2 seconds are selected. But if
we provide an incorrect argument - 1 second is selected.
PFA the patch that adds iteration count argument and makes timespan
argument more consistent.
What do you think?
Best regards, Andrey Borodin.
