Subject: [GENERAL] excution time for plpgsql function and subfunction
Hey List,
kind of a simple question :
I'm using the postgis_topology extension,
and I'm trying to figure where the slowness comes from when importing data.
It involves plpgsql function calling other plpgsql functions, insert, update, etc etc.
I know I can use explain analyze for one querry, but I don't know how to get details of how much time takes each
sub-functioncalled by a main function.
Thus it is very difficult to guess where is the bottleneck.
Thanks ,cheers,
Rémi-C
You could use auto_explain module to get info you are looking for. It'll be logged in pg_log.
Read about it in the docs:
