If you really want to see what's going on, you can also turn on any
of these:
#debug_print_parse = false
#debug_print_rewritten = false
#debug_print_plan = false
#debug_pretty_print = false
The _rewritten one is really interesting, and sometimes shows you why
your query runs slowly. Not recommended for production systems,
though!
Note that all of this exacts a cost, so if you need really blazing
performance, it's not a bad idea to turn it off. But for tracking
down problems, nothing beats a good verbose log.
