Having hit the maximum socketdir length error a number of times in pg_upgrade,
especially when running tests in a deep directory hierarchy, I figured it was
time to see if anyone else has had the same problem? The attached patch is
what I run with locally to avoid the issue, it adds a --socketdir=PATH option
to pg_upgrade which overrides the default use of CWD. Is that something that
could be considered?
