Perhaps explain what you want to do, because from this snippet it is
(for me) definitely not clear.

You're mixing postgresql code (do blocks) and psql commands (\timing).
you're trying to get timing off select, but you're not telling the code
what to do with results of the select.

So, what is the end goal in here? And how will you run it? Via psql?
Some other db access?
