Some more indexterm

Hi all,

During a training course last week, a customer told me he found strange
that current_user is not available on the documentation's index. I think
he's right, so I made this little patch thats adds indexterm tags for
current_database, current_schema and current_user.

Please apply if you find this interesting.

Regards.
