So I was forced to re-do the migration since we had to prepare for a
power outage anyway.  Upon re-running the command, I found out that
the reason I was receiving the notices in STDERR was due to the the
long string of ordered schemas in my search path.  It had a "SET
search_path TO public, x, y, z, ..." at the beginning of the file and
of course schemas x, y, z, etc hadn't been created yet.  So there's no
real cause for alarm after all.
