You have this:

+#ifndef FRONTEND
+   result = pstrdup(str);
+#else
+   result = strdup(str);
+#endif

This kind of thing is no longer necessary.  In frontend, libpgcommon
provides a pstrdup() implementation which is strdup() plus error check,
so you can reduce the above to simply

	result = pstrdup(str);

and it should work everywhere.
