Re: Is the "x ms" info reliable?

When I have pgAdmin, my app, and PG all running on the same machine, pgAdmin reported query times are one or two orders of magnitude slower than times for the same query reported by turning on statement logging.

It's not "pointless time", it's the time taken to execute the query
and for libpq to tell pgAdmin it's done. That is typically what people
want when developing queries that are used in other apps - they need
to see how fast PostgreSQL actually executed it, but not the amount of
time taken to transfer the data to the client which can vary wildly
from client app to client app, especially if running through an SSH
tunnel.
