Thanks for posting your solution, might help another user. As I understand it you're
quoting the variable on the way into MapServer, right? A simpler solution might be
to just adjust your filter by placing quotes around replacement string, like so:

  FILTER "placeref = '%ref_no%'"

That way PostGIS will interpret it as a string.

Solved the problem by adding quote marks at the beginning and end of each
ref_no so that the variable is seem by the map file as a string rather than
an integer.
