Hi, According to the documentation ( http://www.postgresql.org/docs/8.3/interactive/sql-createtrigger.html ), the feaure "SQL allows triggers to fire on updates to specific columns (e.g., AFTER UPDATE OF col1, col2)" is missing. After a bit of research, I found that this feature was in the TODO list ( http://wiki.postgresql.org/wiki/Todo#Triggers ), and that a patch was proposed on 2005/07. Is it going to be implemented soon ? It would greatly help, IMHO, for load, and simplify the write of plpgsql functions called by before triggers. Regards, and keep up the good work, that DBMS (mostly;) rocks !
