Hello.
I’d like to improve pg_stat_statements so that it can report the
timestamp when the stats are reset. Currently it’s difficult to check
that reset timestamp. But this information is useful, for example, when
calculating the SQL executions per second by SELECT calls / (now() -
reset_timestamp) FROM pg_stat_statements.
I’m thinking of adding adding a function called
pg_stat_statements_reset_time() that returns the last timestamp when
executed pg_stat_statements_reset(). pg_stat_statements can reset each
SQL statement. We can record each sql reset timing timestamp but I don’t
feel the need. This time, I’m thinking of updating the reset timestamp
only when all stats were reset.
what do you think ?
Regards.
