Embedding that in encode/decode sounds to me like a pretty horrid idea,
actually, unless I misunderstand what you are talking about.  URL
encoding is a text-to-text transformation, no?  If so, it doesn't fit
into encode/decode, which presume a binary (bytea) decoded form.  People
would be needing to do entirely bogus text/bytea coercions to use
such an implementation.

Ergo, this needs to be a separate function, and so the argument for
putting it in core seems a bit weak to me.  The net field demand for
the feature, so far, has been zero.
