Disallow creating VECTOR indexes on nullable columns#3429
Merged
Conversation
Vector indexes require NOT NULL columns, similar to spatial indexes. Previously, creating a vector index on a nullable column was silently accepted, which could lead to unexpected behavior. This adds validation in both the analyzer (CREATE TABLE) and DDL execution (CREATE INDEX / ALTER TABLE) paths, returning a clear error message. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
