You don't mean me, no ? My comment was intended to give an argument *for*
allowing "= NULL" to behave like "IS NULL", by saying that the "= NULL"
syntax is not defined directly (which Tom Ivar corrected), and would thus
only be an extension.
Tom Lane on the other hand said, that the standard only states NULL as a
constant for a comparison when properly cast to a datatype.
