Hi,
i'm about to implement a trigger on a table with an id field populated by a
sequence (the usual 'id SERIAL NOT NULL PRIMARY KEY').
Just a short (probably lame) question: Would a "BEFORE INSERT" row level
trigger already see a populated 'id' column, or would that happen after all
triggers on the actual insert?
thanks,
Alex

In my experience, all the triggers see all the data all the time in varying
combinations of the OLD and NEW buffers.
