So what you are saying is your small change will cause multiple additional FPIs in WAL. I don't call that a future optimization, I call that essential additional work. +1 on committing the first part of the patch, -1 on the second. I suggest you split the patch and investigate the second part further. -- Simon Riggs http://www.EnterpriseDB.com/
