Viewing access privileges

How can one view all of the access privileges of one or more users?

That is, how can I check what I have GRANTed to whom?

Also, where can I look to find answers to questions such as "what is the
function that returns today's date for a default column value"?

Cheers and thanks,
Stephen Davies.
