Ah, I see now. If you look at Sql.hs, you can see attrs is defined as
a selector function on SqlSelect values. If attrs is applied to some
other value of that type (SqlBin, for example), then you would see
this error. I suspect it's a bug and if you can isolate it  (with
dummy table definitions) that would help a lot.
