Problem: When a LOCK_WAIT_TIMEOUT happened, ANALYZE TABLE ... UPDATE
HISTOGRAM did not report any errors. The command failed silently.

Fix: Do the same as ANALYZE TABLE without HISTOGRAM does: Send any error
that is in the diagnostics area to the client as a result set after
ANALYZE TABLE ... UPDATE HISTOGRAM has completed.
