Ah-hah. Those 1729 extension-owned functions account nicely
for the extra probes into pg_proc, and I bet they are causing
the unexplained getFormattedTypeName calls too. So the
*real* problem here seems to be that we're doing too much
work on objects that are not going to be dumped because they
are extension members. I'll take a look at that later if
nobody beats me to it.
