Description:        strange behave of CHECK constraint
Details: 

Hello,

check constraint doesn't work correct:

opeerator similar works well:

root=# select '233' not similar to '%[^0-9]%';
 ?column? 
----------
 t
(1 řádka)

but:
root=# create table tt(a varchar check (a not similar to '%[0-9]%'));
CREATE TABLE
root=# insert into tt values('233');
ERROR:  new row for relation "tt" violates check constraint "tt_a_check"
