pub fn required_extensions(target: &SchemaDescriptor) -> Vec<&'static str>Expand description
Postgres extensions target needs in order for its own DDL to apply
cleanly — currently just vector (pgvector), needed the moment any
type declares a vector index. Extending this to a future
extension-dependent feature is just adding another check here; the
caller-facing surface (missing_extension_ddl) doesn’t change.
