This extension format is still incorrect, as there is no need for
dblink--1.1.sql as on the latest version of an extension needs to be
supported, and Makefile needs to be updated in consequence. Please
find attached an updated patch.

+-- fetch using anyelement, which will change the column names
 SELECT *
-FROM dblink_fetch('rmt_foo_cursor',4) AS t(a int, b text, c text[]);
- a | b |     c

Why isn't this test case not left alone? It looks like a regression to
me to not test it.
