Thread: read/write statistics on a table

Are any maintained within the database that can be queried/viewed?

Ack, had read it, but skim'd over it too fast :(

one question I do have, that I'm not finding on the page ... are these
stats since the postmaster started, or are they kept across reboots?  I'm
suspecting since start, else the I/O used by the collector would
presumably get *very* busy having to write the data to the disks, but ...

You can have it either way --- there's a GUC var that determines whether
the stats are reset at postmaster start.
