The test case is failing on one of the build farm machines. See email
from Tom Lane [1]. The symptom clearly shows that we are decoding
empty xacts which can happen due to background activity by autovacuum.
I think we need a fix similar to what we have done in
https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=82a0ba7707e010a29f5fe1a0020d963c82b8f1cb.

I'll try to reproduce and provide a fix for this later today or tomorrow.
