Uh, just to clarify, this has nothing to do with how long the operator has
been deprecated.  The issue is whether pg_dump should dump a function-call
syntax that will not be recognized by any pre-9.5 release, when there is
an alternative that will be recognized back to 9.0.

BTW, I just noticed another place that probably should be changed:

regression=# select foo(x => 1);
ERROR:  42883: function foo(x := integer) does not exist
LINE 1: select foo(x => 1);
               ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.
LOCATION:  ParseFuncOrColumn, parse_func.c:516

1. funcname_signature_string
2. get_rule_expr
