You're making it vastly overcomplicated. Just do something like
for (cp = str; *cp; cp++)
{
if (*cp == '\\' || *cp == '\'')
AppendStringInfoChar(buf, '\\');
AppendStringInfoChar(buf, *cp);
}
Since you're working in a server-safe encoding, there is no need to
worry about multibyte characters --- the tests will never match
any byte of a multibyte char.
