It might've been a tad more efficient to return
the StringInfo buffer directly from pgp_armor/dearmor, and avoid the
extra palloc and memcpy, but this isn't performance critical enough for
it to really matter.

I couldn't see any way of doing that without breaking the VARDATA
abstraction.  I even went looking for similar cases in the source code,
but couldn't find any.  If you can come up with a way, feel free to
change that -- I'd like to learn myself.

You could first append VARHDRSZ zeros to the StringInfo, then append the
base64-encoded data, and last replace the zeros with the real length,

That's assuming that VARDATA() is at exactly VARHDRSZ bytes. I couldn't find any callers making that assumption.
