My database has shutdown several times in the last couple days.  I have no

any configuration changes.  I am running postgres 8.2 and it has been
stable since I installed it about 5 months ago.  The databases crashes and
so my software application goes down.  When I restart my application
everything seems to work fine.  But then it crashes again, something
appears to be corrupt.  Here are my logs:

TIP 6: explain analyze is your friend

 

Looks like someone is doing a kill -9 on one of the database processes causing postgres to do a restart.
