I think aligning those is a good idea. I had just been wondering to
myself last night about how much binary space is taken up by needless
additional string constants that could be normalised a bit.
Translators might be happy if we did that.

Yeah. I went with reporting the objtype that was specified in a
command. I stayed well clear of allowing overlapping names between
procedures and functions. It would be hard to put that back if we
ever discovered a reason we shouldn't have done it.
