Ugh. That used to work more nicely:
regression=# create index fooi on foo ((row(a)));
ERROR: column "pg_expression_1" has pseudo-type record
But that was back in 8.4 :-( ... 9.0 and up behave as you show.
I'm guessing we broke it when we rearranged the rules for naming
index expression columns.

Haven't read the patch in any detail yet, but that seems like
an improvement. And I guess we need a test case, or we'll
break it again :-(
