Обсуждение: Files in pg_xlog

Hi everybody!

Does anybody knows how can I change the size (something about 4Mb) of
the files inside the pg_xlog directory and how can I have no more than
one file inside it.

Would be nice a quick explanation about the efects of it.

Thanks for all

You can't, short of hacking the source code (and I'm not sure it's a
one-line change if you do...)

Can't do that either.  In a low-traffic database you could reasonably
expect to have no more than two xlog files most of the time.  Set
checkpoint_segments to 1 to minimize the space usage.
