Ah --- probably back in 7.1, the backend's automatic output-column-name
selector was not bright enough to dig down inside typecasts.
Your patch (assign the column name explicitly) is a good one.
This brings up a more general issue, which is that we need to test
pg_dump against old backend versions as well as new ones. I had had
a private "todo" item to run some tests of that sort for 7.3, but never
got 'round to it.
