My understanding is that the mysql server is at a Linode facility in PA,
the current production postgres server is in Asheville NC, and the intended
new server is a Azure server in the eastern US, not sure exactly where.

The two small matviews refresh, the two bigger ones fail, so it seems
size-related, which is why I was wondering if the settings might make a
difference because this server isn't fully production-scale yet.  But
weve transferred 175 GB files to it in about 6 hours so I think the net
connection itself is probably not the issue.
