Get the statistics based on the application name and IP address
While working on pg_stat_stements, I got some questions from customers to
have statistics by application and IP address. I know that we are collecting the
statistics by query id, user id, database id and top-level query. There is no way to
collect the statistics based on IP address and application name. That's possible that
multiple applications issue the same queries with the same user on the same database. We
cannot segregate those queries from which application this query comes. I know we can
this in the log file with log_line_prefix, but I want to see that aggregates like call count based on IP and application
name. I did some POC and had a patch. But before sharing the patch.
I need to know if there has been any previous discussion about this topic; by the way,
I did some Googling to find that but failed.
Thoughts?
