Ah-hah, now it makes sense. I believe the JDBC driver always uses
extended query protocol (parse/bind/execute messages). We know that
that code path is a bit shy of a load with respect to statement logging,
mainly because no one has worked out exactly what it ought to log and
when. When you consider the possibilities for re-use of parsed
statements and partial execution of portals, it's not clear what a
"statement" is, let alone what its "duration" is. Maybe the real
problem is that the GUC variables are defined in terms of a too
simplistic view of the world.
As a quick workaround until someone thinks of a better idea, it might be
sufficient to attach logging code to the execute phase, and ignore the
partial-execution issue.
