The first one you posted looked correct. This line above seems to have
problems. I think you want this:
PERFORM distinct COLUMN1 FROM TABLE where COLUMN1 = '''' ||
quote_literal(VARIABLE1) '''' || '' AND COLUMN2 = '' || '''' ||
quote_literal(VARIABLE2) || '''';
Generally PERFORM is used for side effects only. I don't see why you
would use PERFORM unless this line will change the database somehow.
