This patch has not included all pg_catalog compatibility fixes from datafusion-postgres. We will update again when we upgraded to datafusion 50.

A summary of this patch:

• replaced all pg_catalog implementation with datafusion-postgres
• bridge between our API with datafusion-postgres: mostly for reading recordbatches from datafusion tables
• register UDFs and UDTFs
• fix an issue with sqlness runner on postgresql output
• update sqlness results for these tables
• use datafusion-postgres sql rewriter to rewrite sql into the form that works with datafusion
• update parser to support sql rewritten by postgres dialect (FETCH n IN CURSOR, show )
• use patch.crate-io to include our datafusion fork, so it overrides all datafusion 49 in our dependency tree.
