If you can change the application then one option is to set application_name so that it contains API function name. This should happen before the first call in API function hits the database. After the API function finishes it should reset application_name.
Then you can enable logging of all queries and set the format to include application_name parameter. This way every query is logged and each log entry has an application name. Several things to keep in mind: 1. logging everything may affect performance 2. application_name is 64 chars by default Regards, Roman Konoval rkono...@gmail.com > On Sep 13, 2018, at 21:49, Fd Habash <fmhab...@gmail.com> wrote: > > In API function may invoke 10 queries.
