Qty of WAL files
Hi chaps,
I've set the checkpoint_segments on our system to 20 in anticipation of our system being quite write heavy, and I was wondering if someone could give me the lowdown on the amount of WAL files created and how they're re-used.
I've just read in a large amount of data into the database and as expected quite a few WAL files were generated.
Will the amount of WAL files ever be decreased automagically?

(Adjust link for your PG version, as the rules were different in earlier
versions.)
