I'm only clueless about the details of pg, not db perf concepts. Really,
a mechanism to determine where the system is spending the response
time is key. As you pointed out, the added table may not be the issue.
In fact, if you can't measure where the db time is being spent
you will be lucky to fix a performance issue, since you don't really
know what resources need to be addressed.

this afternoon, maybe.
