I noticed there's 66 files in my pg_xlog directory. I changed my

How can I get this list of files down?
A checkpoint after there's been some write activity in the database
should reduce this down to a reasonable number. If the system has been
idle since the last checkpoint, it doesn't do anything when you ask for
another one, which includes skipping this cleanup; that may be why you
haven't seen it drop yet.
I'm assuming you don't have WAL shipping turned on by setting
archive_command. There can also be an excess of these segments that
can't be cleaned up if your archiving scheme fails.
