Hi everybody

Current tests with regexp_instr() and regexp_substr()  with string 
'abcabcabc' are really unreadable and you would spend time to understand 
that happens in these tests and if they are really correct. I'd better 
change them into "abcdefghi" just like in query

     SELECT regexp_substr('abcdefghi', 'd.q') IS NULL AS t;
