OK, failr enough...

But what about:

Could I please get a definitive answer about this?

David, in the "clone-schema" thread, you kind of implied I shouldn't
have a set search_path in the triggers,
thus making my DDL schema-specific, but then when I ask about ways to
avoid thus, and have "static" resolution
of names in those trigger functions, I'm not getting alternatives.

Am I the only one to think that a session w/o a seach_path, which
fully qualifies table names,
should behaves exactly the same way than another session that has a
search_path and does not fully qualify table names?
Because that's the only reason I added a set search_path to our
trigger functions. The alternative being to fully-qualify
all object references in those trigger functions, making the DDL even
more "schema-specific". it feels like a catch-22...

I'm not trying to be difficult here... I'm trying to understand, FWIW. --DD

PS: Does INVOKER vs DEFINER affect name resolution? Does that apply to
trigger functions?
