Everyone please excuse the mistake in my previous
question, there is a lot in my mind.
We are already creating a complete backup every day,
and would like to have WAL files to restore up to the
last minute of course.
Acording to
http://www.postgresql.org/docs/8.1/s...RCHIVE-COMMAND http://www.postgresql.org/docs/8.1/s...-ARCHIVING-WAL
I tried a couple of them and got an error messages
stating that WAL archiving was not activated, so, how
can I activate it? thanks
these docs explain a lot but are not practical like
the ones in howtoforge.com for example
In regards to my previous question, I did not check
what I wrote, what I meant is that the 16*1024*1024
WAL file size is too big for us because we handle just
a few KB per day of information, so are interested in
a smaller WAL file size, perhaps 1024*1024 or even
less so that we can backup the files in less media
space, but in the
postgresql@freenode.net IRC channel
I was told that I would make the database work slower
if I make a WAL file too small, what is your take on
the matter? recomendation? etc?
thanks a lot!
