posters regularly break threads. Why can't you create a new mail for
a new topic without replying to another mail with a totally different

The PostgreSQL WAL log stores information on the level of "write these

You might be able to do some kind of thing like:

Hi!
I'm having problems trying to install the PHP module for Apache2.
It seems it requires libpq.so.4 but the latest 8.0.3 PostgreSQL version
doesn't include it -- though it does include a libpq.so.3.
How can I fix this problem?
Thanks!

Hi,

I have started Postgresql (8.0.3) on the laptop and have

I would like to keep them reasonably in sync. Slony is
overkill and I think the "mirror" contrib
