Is there an echo in here?
To be fair, Dave's point is that times from a client's perspective will
necessarily be longer than those from inside the server. That doesn't
account for an order of magnitude's difference though, especially when the
connection is local. I too think that pgAdmin is counting the time to
traverse the result set, but that's purely speculation.

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.
Yeah, I agree with the OP. I'm pretty sure the time the query tool reports
includes the display time. I didn't check in the code, but that was always
my view of the time. Doesn't mean it is useless, but pretty much like it.

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.
