Only problem is, a "select count(1)" is taking a long time. Indexes
shouldn't matter with this since it's counting every row, right? The
tables are fairly well indexed also, I could probably add a few more.
If shared_buffers isn't the way to go ( you said 10k is the sweetspot
), then what about the effective_cache_size? I was suggested on the
general list about possibly setting that to 75% of ram.
Thanks.
