As there are now 3 locking times on pgss hash struct, one day or an other,
somebody will ask for a GUC to disable this feature (to be able to run pgss
unchanged with only one lock as today).
With this GUC, pgss_store should be able to store the query text and
accumulated
execution duration in the same call (as today).
Will try to provide this soon.
