It does ... master being dd498998a3 here,

$ patch -p1 < /tmp/renametrig-8.patch 
patching file src/backend/commands/trigger.c
patching file src/backend/parser/gram.y
patching file src/test/regress/expected/triggers.out
patching file src/test/regress/sql/triggers.sql

applies fine.

Well, it does rename a trigger named 'name' on the table 'table_name',
as well as all its descendant triggers.  I guess I am surprised that
anybody would rename a descendant trigger in the first place.  I'm not
wedded to the decision of removing the NOTICE, though  ... are there any
other votes for that, anyone?

Thanks
