Help supressing NOTICE messages

Hi All,

I'm developing some scripts to create my schema to be run by other
developers and I'd like to have them not spit out those NOTICE messages
when you create a table regarding the implicit indexes that are made
since it just makes it harder to see when there is a real error.

I've tried running psql with the quiet argument, I've set the QUIET
variable to true and the VERBOSITY level to terse but the NOTICE
messages still appear(while all other output is supressed).

I searched the archives and found one post from a developer where he
stated that this is a feature that's been asked for and would be
available in 7.3 and I have 7.4.5.

Other than that I haven't been able to find any documentation or mention of it.

Can anyone point me in the right direction?

Thanks,
Alex
