https://github.com/apache/arrow-adbc/pull/4775 is an experimental PR that adds an option to only use a hardcoded set of OIDs, eliminating the need for any query on startup. Before merging I plan to add a basic fallback where it will build the type table if needed when a query requires it; longer-term we would build the type table on-the-fly instead of requesting everything up front. In Postgres, every table is automatically a composite type which unfortunately means that it's hard to optimize the underlying query in a fully correct way (although most likely, the vast majority of tables are never used in such a way, we have no way of knowing up front). -- This is an automated message from the Apache Git Service.
