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. > For example, the attached patch makes it this: > create index on foo ((row(a))); > ERROR: column "row" has pseudo-type record 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 :-( regards, tom lane
