We definitely want this feature, I wished to have this info many times.
I would still like to see a benchmark.
Average of 3 runs of read-only pgbench on my system all with
pg_stat_statement activated:
HEAD: 20631
SQRT: 20533
SQRTD: 20592
So using sqrtd the cost is 0.18%. I think that's acceptable.
I think so too.
I found one more issue with the 1.2--1.3 upgrade script, the DROP
FUNCTION pg_stat_statements(); should be DROP FUNCTION
pg_stat_statements(bool); since in 1.2 the function identity has changed.
