Description

Once we're unable to crash postgres easily ourselves we should use SQLsmith to run a bunch of randomly generated queries. If these cause errors or don't work, that's "fine" but they shouldn't be causing crashes.

Contributor guide

Research direction
Set up SQLsmith to generate random SQL queries and run them against pg duckdb; monitor for crashes and report any that occur. Focus on edge cases and complex queries.
