I'm not for or against back porting this feature. I basically want to
know if my plan (appended to this email) was a sane way to write
forward-compatible code.
I can't rely on PQescapeString, because the client library may be a
different version than the server. Right?
The only other logical option is to make a wrapper function around two
string-escaping functions that checks the server version and creates a
string accordingly.

PS: my plan for making an E'' like string in 8.0:
CREATE FUNCTION ein(CSTRING) RETURNS E AS 'textin' LANGUAGE internal;
CREATE FUNCTION eout(E) RETURNS CSTRING AS 'textout' LANGUAGE internal;
CREATE TYPE E (input=ein,output=eout);
CREATE CAST (E AS TEXT) WITHOUT FUNCTION AS IMPLICIT;
CREATE CAST (TEXT AS E) WITHOUT FUNCTION AS IMPLICIT;
