There are many different ways to avoid or minimise the chance of schema
disagreements, the easiest way is to always send DDL queries to the same

disagreements at the cost of creating a single point of failure for DDL
queries.

thought that temporary schema mismatches were eventually resolved smartly,
by a kind of "merge" mechanism.
