Hi.
This is a proposal for a new feature in pg_stat_statements extension.
I think we need to add some statistics to pg_stat_statements_info view.
"pg_stat_statements_info.stats_reset" will only be logged if
"pg_statements_reset()" or "pg_statements_reset(0,0,0)" is executed.
How about changing it to the following ?
[before]
-[ RECORD 1 ]------------------------------
dealloc | 0
stats_reset | 2021-04-27 21:30:00
[after]
-[ RECORD 1 ]------------------------------------------
dealloc | 0
last_reset_all_time | 2021-04-27 21:30:00
last_reset_userid | 10
last_reset_userid_time | 2021-04-27 22:30:00
last_reset_dbid | 13974
last_reset_dbid_time | 2021-04-27 23:30:00
last_reset_queryid | 8436481539005031698
last_reset_queryid_time | 2021-04-27 23:30:00
If "pg_statements_reset(10,0,0)" is executed, then "last_reset_userid",
"last_reset_userid" are updated, but do not update
"last_reset_all_time".
If "pg_statements_reset(0,0,0)" is executed, then "last_reset_userid",
"last_reset_userid" and others are null.
What do you think?
Regards,
Seino Yuki
