It sounds like you are wanting to run 'explain analyze [query]' inside a loop inside a DO block. That isn't possible as far as I know, but auto_explain and log_nested_statements should be able to let you profile the whole thing and perhaps you can pick out the part you want from the logs.
I believe it can be done technically, though basically the function will need to be re-written for the purpose. It isn't as simple as adding an explain somewhere since the output of explain is a result set. But as you are already using pl/pgsql then your parameters can just be done up as variables instead and that query should be able to be explained.
