GRANT in pg7.2

Hi,

I need some help for the following:

Is there a way I can assign EXECUTE privilege for a user-defined function in the GRANT command in 7.2? (7.3 has it)

Also, how do I list all the user-defined functions/stored procedures. Once listed, how to give UPDATE privilege to a user on all of them?

Appreciate any help.

Thanks,
Anjan
