Pekka Enberg	6199c3994a	Merge 'Create plan for Update queries' from Preston Thorpe ... closes #1186, or at least works towards it by implementing an actual Plan for update queries instead of translating everything inline. This allows for actually using index's, rewriting const expressions, pushing predicates instead of hardcoding a full scan in the translation. ### TODOs: 1. `RETURNING` clause/result columns 2. `OFFSET` clauses 3. on conflict ### LIMIT: By supporting `LIMIT` directly in update queries, we'll have to put the tests outside of the compatibility tests, maybe in the CLI tests.
