I just finished reviewing 0007 and 0008. This patch set really demonstrates the full lifecycle of adding a SQL feature,
fromchanging the syntax in gram.y all the way down to the executor, including tests and docs. I learned a lot from it.
Thanks!

23 - 0007

As you mentioned earlier, pattern regular expression support *, + and ?, but I don’t see ? is tested.

24 - 0007

I don’t see negative tests for unsupported quantifiers, like PATTERN (A+?).

25 - 0007
```
+-- basic test with none greedy pattern
```

Typo: “none greedy” -> non-greedy

No comment for 0008.
