Ok, here's what I came up with (with time to test it).
If the query took less than a second, timing display is unchanged.
Otherwise, print the ms time, followed by a more human readable form
accurate to 0.001s.
# select 1; select pg_sleep(1); select pg_sleep(71); select pg_sleep
(3601); select pg_sleep(24*3601);
?column?
----------
1
(1 row)
Time: 1.575 ms
pg_sleep
----------
(1 row)
Time: 1002.568 ms (1.003s)
pg_sleep
----------
(1 row)
Time: 71041.022 ms (1m 11.041s)
pg_sleep
----------
(1 row)
Time: 3601083.544 ms (1h 0m 1.084s)
pg_sleep
----------
(1 row)
Time: 86424018.416 ms (1d 0h 0m 24.018s)
As-is, there isn't much that could be done for regression or documentation
changes, so I'll just leave this here.
