Re: BUG #18218: NOT LIKE ANY returns same result as LIKE ANY when array items are wrapped into E''

No, it is not.  "NOT LIKE" is the operator to apply in this context,
so the second expression returns true if the test string is NOT LIKE
either of the array elements.  You could write

NOT ('TextToMatch' like any (array[E'Te\%tch', E'nomatch']))

to get the behavior you are after.  Or write NOT LIKE ALL,
as Orlov suggests.
