That doesn't really answer the question, though, since none of
7.4/8.0/8.1 interprets '' strings in a strictly standards-conforming way
as I understand it.

The impression I got from previous discussion was that you need to check
the value of the standard_compliant_strings GUC, and double backslashes
inside '' only if it was false or missing.
