Random not so random - Mailing list pgsql-general

Hi everybody,

I'm doing the following query:

   select * from messages order by random() limit 1;

in the table messages I have more than 200 messages and a lot of times, the
message retrieved is the same. Anybody knows how I could do a more "random"
random?

Thank you very much
