Pushed with minor adjustments.  I thought a couple of variable names
could be better chosen, but mostly, you can't do this sort of thing:

-            psql_error("The server (version %s) does not support editing function source.\n",
+            psql_error("The server (version %s) does not support editing %s.\n",
                        formatPGVersionNumber(pset.sversion, false,
-                                             sverbuf, sizeof(sverbuf)));
+                                             sverbuf, sizeof(sverbuf)),
+                       is_func ? "function source" : "view definitions");

It's too much of a pain in the rear for translators.  See

Usually we just use two independent messages, and that's what I did.
