As of the out-of-support 8.3 release many of the implicit casts previously
defined have been changed to explicit casts.  It is a catalog change -
obviously, since you can still define implicit casts - so if you absolutely
must have the pre-existing cast be implicit you can modify the catalog
directly.

You may wish to describe why you think this is the solution you need - with
implicit casting there are generally more downsides that upsides.
