Subject: [PATCH] Support .toPostgres() on Array-derived objects
Related to #2012.
Since we cannot disambiguate between Arrays that should be converted to
PostgreSQL array types and Arrays that should be treated as JSON, make
it at least possible to define custom Array-derived types.
This also makes it possible to properly serialize Array-derived
multirange collections where elements must not be independently escaped.
