You've declared thisrow to be point_table%ROWTYPE, which is presumably
something like (integer, ..., geometry).  The cursor's select list
has a single text column; FETCH INTO is trying to store that text
column in thisrow's first column (an integer) so you get a type
mismatch.  Declare thisrow to be of type record, or declare it to
be text and return thisrow instead of thisrow.geom.  Examples:

  DECLARE
      thisrow  record;

or

  DECLARE
      thisrow  text;
  ...
      RETURN thisrow;
