Was this a VACUUM ANALYZE, and if so might there have been another
ANALYZE running concurrently on that table? If so, this is just a
reflection of concurrent attempts to update the same pg_statistic
row. It's harmless since the ANALYZE that didn't fail presumably
stored pretty nearly the same results. There is some interlocking
to prevent the error in CVS HEAD, though.
