Numeric are cast to text in JS (instead of number)

Here's a little reproduction:

```
SELECT 42::text;
SELECT 42::numeric;
SELECT 42::integer;
```

When this run on https://pglite.dev/repl/, I get:

Notice how the numeric is aligned to the left as it's considered text

When this run on https://onecompiler.com/postgresql, I get:

Numeric is correctly aligned to the right.

This is just one way of seeing the bug, my main concern is in JS, after doing a SELECT, I get a string instead of a number.
