How to make backups of PostgreSQL?
Recently someone was looking for help with script from Pg wiki.
I never really checked it, but when talking with the guy needing help, I looked at it. And didn't really like it.
What is the overhead of logging?
update at the end of the post!
There obviously is one – after all, logging information has to be more expensive than not logging it. But how big is it? And more importantly, what is the difference between logging to stderr/file, csvlog and syslog? And what about syslog to remote machine?
Let's see.
Pick a task to work on
There is new blogpost on this subject!
There are cases where system stores list of things to do, and then there are some worker processes that check the list, pick something to work on, do it, and remove from the list.
Proper solution is to use some kind of queuing system. There is even PgQ which works withing PostgreSQL, but some people are not happy with it, as it requires compilation and installation. So they just use plain selects.
Will that work OK?

Waiting for 9.4 – WITH CHECK OPTION support for auto-updatable VIEWs
On 18th of July, Stephen Frost committed patch:
WITH CHECK OPTION support for auto-updatable VIEWs For simple views which are automatically updatable, this patch allows the user to specify what level of checking should be done on records being inserted or updated. For 'LOCAL CHECK', new tuples are validated against the conditionals of the view they are being inserted into, while for 'CASCADED CHECK' the new tuples are validated against the conditionals for all views involved (from the top down). This option is part of the SQL specification. Dean Rasheed, reviewed by Pavel Stehule
