Comment:

 Strk where does the MIGRATION guide say geometry_columns don't use
 constraints.
 I think the confusion might have been where I said views built the old
 constraint way (when I should have said views with base tables built the
 old constraint way).

 I hope I clarified this in 7561 and also tried ot change to 80 column.

 Tables that use constraints are registered right.
 Views that are based on tables that used constraints do not get registered
 right since the constraints don't carry to the views.
 Views based on typmod geometry columns may or may not register right.
 They will if they are not passed thru geometry processing functions.  They
 won't if you apply a processing function to them.

 These can be remedied by casting them to the appropriate typmod type.
