An other way is to use "waits" reporting ...
something like :
pgss_store (...)
pgstat_report_wait_start(PG_WAIT_EXTENSION);
...
pgstat_report_wait_end();
gives waits of type "Extension", name "Extension" when spending time in this
part of pgss.
This can help those working
Don't you have been surprised by the duration of a query (seen in psql with
\timing)
and the duration for the same query found in pgss ?
It seems that writting the first query text to file takes some time,
that high execution rate on the same query could generate waits on locks
as when pgss is u
