It took me way too long to figure this out:
SELECT 'text to search against' ~* 'regular expression'
The text to be searched must be on the left-hand side of the operator and
thus the regular expression operators cannot be used with "ANY/ALL" because
they require that the text to be search exist on the right-hand side of the
operator.
I'll let others respond as to the difficulty of implementing a LHS-Array
version of ANY/ALL
