These ~~ (LIKE) tests on date columns seem horribly unsafe.  I suspect
your problem is that you're trying to load the data with DateStyle
set to some setting other than what this constraint is hard-wired
to assume.  Personally I'd suggest replacing the LIKEs with something
using EXTRACTs, or some other way that doesn't depend on the textual
formatting of dates.
