Well, the current ordering is definitely historical rather than
designed, but I'm hesitant to do more than minor tweaking. Even if we
think/hope it won't break applications, people are probably used to
seeing a particular ordering.
I'm not necessarily dead set against it though. I guess if we were
to do what you suggest, we'd end up with
identity:datid | oid | datname | name | procpid |
integer | usesysid | oid | usename | name |
application_name| text |
session:client_addr | inet | client_port | integer | backend_start |
timestampwith time zone |
transaction:xact_start | timestamp with time zone |
query:query_start | timestamp with time zone | waiting | boolean | current_query |
text |
or possibly that plus relocate procpid somewhere else. Anyone think
this is sufficiently better to justify possible confusion?
