Description

Add a guardrail to allow operators to toggle support for the new Vector type. This is a precaution that operators may desire when working with clusters than have a diverse set of clients, and some clients may not yet support the new vector type. Those clients may fail when fetching metadata ("unexpected column type") and prevent session establishment, or fail to query vector columns, or otherwise behave strangely.
