Interesting -- both yak and snake are failing in a very similar way.
I'll investigate it tomorrow if no one beats me to it.
All our Windows buildfarm machines are failing.  AFAICT, the first
failure was on Yak,

and the last successful run just before that seems to come from Snake,

The only changes that went in in that period are the patch that enabled
autovacuum by default, an information_schema fix and a TODO file change.
The only that could cause this problem seems to be the autovacuum enable

I think this one:

is fallout from the autovacuum changes too - it seems that initdb is
picking a low value (20) for max_connections on that box and autovacuum
is acting as an additional client that will cause the maximum of allowed
connections to exceed during the parallel tests and therefor resulting
in the failure.

If so, that's a case of driver error, I think. The buildfarm member should set MAX_CONNECTIONS => '10' or similar in the build_env stanza of the config file.
