Track currenctly logged in user in trigger

Hi,

I want to set a specific field on every update to the username currently logged in.
Is there something like 'now' for the username or so?
At the moment, we already set a timestamp in the trigger,
but want to include the username, too, to
keep track of who made changes to which tables, etc.

thanks for any help,
Daniel Albuschat

you can use:
CURRENT_USER
CURRENT_ROLE

Thanks, that was exactly what I was looking for.

cu, Daniel
