Hello again,

This is working ! Thanks...
Is it better to use varchar as parameter, or just "text" ?  The colmuns I'm 
updating through this function are varchars.
I'm still surprised about 1 thing : it seems PostgreSQL is not checking for 
existing tables or columns.

Like this :         UPDATE tbl_table_last_change
            SET last_user = current_user,

Table tbl_table_last_change doesn't exist yet, but still postgreSQL is 
acception the function definition...
So, I guess, there is no early checking on tables/fields ?

Thanks for your help, for sure I would never find the solution, I had no 
idea about the casting...

Best regards, Nico
