Unfortunately, that just says that the failure is intermittent, which is
pretty much exactly what you'd expect from not-quite-right locking code.
Try running the parallel regression tests several times in a row.  (The
serial test mode is unlikely to exhibit any problem.)  I tend to do this
by installing the test postmaster and then doing "make
installcheck-parallel" over and over, rather than repeating "make
check"; repeatedly building a test installation is just wasting time
for this sort of thing.
