[GENERAL] VACUUM and open transactions

[Joseph Shraibman]

I'm running postgres 8.0.8.  I have a table that is updated very 
rapidly, so I vacuum it every 10 minutes.  The problem is that I 
sometimes have transactions that hang out for a long time without doing 
anything.  These transactions are preventing VACUUM from cleaning up 
tuples that were created and then deleted in transactions that started 
way after the hanging one.  Is there any way to fix this?
