Subject: Incomplete compatibility information for triggers
Date: Sun, 11 Nov 2012 21:52:52 +0100
Message-ID: <[email protected]> (raw)

Hello,

the compatibility section of the "create trigger" page 
(http://www.postgresql.org/docs/devel/static/sql-createtrigger.html) 
claims that a missing functionality is the ability to define aliases for 
the "old" and "new" rows or tables. If I am understanding this 
correctly, another related missing functionality is that PostgreSQL does 
not allow the old and new tables to be referenced for statement-level 
triggers (i.e., the "OLD TABLE" that contains all the deleted/modified 
rows in case of deletion/update). I think this is also worth noting as 
any workaround for it seems to be more difficult (if possible at all) 
than for the missing alias feature.

Regards,

Louis-Claude Canon
