This returns a string with text '95b...', '...', '...'

This is three values.

You could either use strpos() on the raw string (as long as you know you
 won't get partial/multiple matches). OR split the string to an array:


SELECT 1
WHERE
'95b5a221aeba15c' = ANY(
  string_to_array(
    '95b5a221aeba15c+fb4e7219ab898ce+b08586cb81059f9',
    '+'
  )
);
