Wow! is this standard ?
I found the function trim by doing 'select oprname from pg_oper'
and tested it as follows:
hannu=> select trim(' x ');
btrim
-----
x
(1 row)
why is the column called btrim ?
some rewrite magic in parser ?
If it must stay a keyword, then perhaps we should remove the proc ?

yep! Thanks:
create table test2(a text,b text, check (btrim(a) <> '' or btrim(b) <>
''));
does work ;)
