I find this patch mighty ugly, and hope that most of it can get reverted
before 8.2.  The changes you made in describe.c are actively broken ...
didn't you test it?  appendStringLiteralConn doesn't know what you did.

I think that a far saner approach would be to make all these places use
appendStringLiteralConn, and to change *only* that routine to throw on
an E at need.  That would (a) not be broken, and (b) give us just one
place to change the behavior when it comes time.
