`dolt_patch` needs adjustments for postgres syntax

1. Schema changes (like `create schema`) should be included in the returned statements (see test [here](https://github.com/dolthub/doltgresql/pull/788/files#diff-0e36453b367b9dc8ec661fb2a606435f8a4bc9f75787f9385ac723aeee34533aR392))
2. Returned statements use mysql syntax instead of postgres (like backticks instead of double quotes, etc) (see test [here](https://github.com/dolthub/doltgresql/pull/788/files#diff-0e36453b367b9dc8ec661fb2a606435f8a4bc9f75787f9385ac723aeee34533aR400))

Also statement order is not consistent when there are changes to tables in more than one schema
