Hi,
I am trying to integrate a tracing framework in the Postgres code.
I need to know if elog.c under backend/utils/error is the place where
the changes can be made.
It depends: what exactly are the kinds of events you want to trace?
If you're looking to redirect the logging output Pg can already produce,
you can just have your tracing system act as a syslog daemon and get
postgresql to write to syslog. If you want something more detailed, elog
will probably do much of what you need.
If you want to trace things like actual row changes, which Pg never
writes through elog, you won't be able to get them via that mechanism.
