Take a look at the script repro-bogus-subtrans-error-wraparound.sh
from this email:

That used pg_resetxlog -x $XID $PGDATA, but needed to do several hops
stop/pg_resetxlog/start hops to get all the way around the xid clock.
Thanks Thomas. I ended up figuring out something similar after I read the docs on pg_resetxlog.
It did something interesting to two of my local databases, but I was able to figure out what I wanted to know.
Thanks again!
