A quick grep reveals that the places that still do it that way are
OperatorShellMake
OperatorCreate
TypeShellMake
TypeCreate
update_attstats (though this one might be hard to improve)
CreateComments
CreateSharedComments
InsertRule
Of these, all but the two in comment.c follow the convention of
mentioning the assigned-to column in a comment, so that the code
is at least somewhat greppable. So those two definitely need
improvement, but should we consider changing the others while at it?
BTW, there are some contrib modules with functions-returning-record that
fill in result tuples this way as well. But we don't have symbolic
constants for the column numbers there, and it's probably not worth
introducing such.
