Thread: Current User

Hi,

I want to have a table to manage  a register of the modifications made to
several tables by a group of users, that table should contain the name of the
postgres user that made the modificaction, now, How can I get the name (or
the user id) of the current user logged in?,there are some "pg_currentuser"
table to make a select?

I would thank any help.

Look at insert_username in contrib/spi.  Basically you create a trigger
on insert.
