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.
Best regards,
