Re: Add jsonb_translate(jsonb, from, to)

Hi Florents,

Thanks for the patch. I once had the same pain on a similar task, I had to create a PL/SQL function at the time.

I haven’t read the code change yet, but I think the function name jsonb_translate() sounds to generic. To make the name more meaningful, I would suggest a few candidates: jsonb_replace_text(), or jsonb_replace_value(), or jsonb_deep_replace().

Also, I want to understand why do you decide to support only whole word matching?

```

evantest=# select jsonb_translate('{"message": "world"}', 'wor', 'earth');

   jsonb_translate

----------------------

 {"message": "world"}

(1 row)

``` 

With this patch, partial match will not result in a replacement.

This is a spur of the moment patch really,

but while going through the process of translating some json data from Greek to English I found myself wishing for $subject.

Inspired by the Unix tr utility.

Here's a working v1

If others find it useful as well,

I'd go ahead with a json implementation 

And an additional parameter to make in-arrays replacement optional.
