Review comment:
:) I tried this, but it turns out that `getText` strips the spaces. Thus
this comment:
```
// Extract the raw expression text so that we can save the user provided
text. We don't
// use `Expression.sql` to avoid storing incorrect text caused by bugs
in any expression's
// `sql` method. Note: `exprCtx.getText` returns a string without
spaces, so we need to
// get the text from the underlying char stream instead.
```
