union and limit - Mailing list pgsql-general

Hi All

i tried to send the following querry:

select * from table limit 3,0 UNION ALL select * from table limit 3,0;

This querry returned me an error so i put each select in parenthesis and it
worked.

Is this the way to solve it ?
if it is, i think it should be in the docs.
