Huh, sorry, this doesn't work ... we don't allow DECLARE for EXPLAIN. It'd be neat though ...
What about having a debug mode for the function. E.g:
selet * from foo('bar','debug')
When you run with debug it actually runs the function but outputs notices that are the explain anaylze of each function? You might I would have to check be able to include a timestamp at the beginning of each notice.
This will allow you to figure out where your slow downs are that are not query related?
Sincerely,
