* refactor: use analyze to get statement params * feat: use analyze to describe statements * fix: get param index from param name instead of index in list * test: add more tests * test: add more tests + disable clirr Disabling clirr as it only adds noise, and somehow refuses to pick up the latest ignore. * chore: cleanup * fix: update test for analyzeUpdate * fix: disable flaky assertion * fix: remove accidentally committed folder * fix: remove more assertions pending node-postgres 8.9 * fix: disable more assertions awaiting 8.9
