I recall something along those lines existing once in the extension
world. Or maybe just from a previous employer. I don't recall many of
the details. Maybe something like a function you pass an SQL string
and if you cancelled the query it reported the EXPLAIN ANALYZE done so
far. I assume it must have done something like LOG it as it couldn't
have shown the EXPLAIN as query results on cancel.
