Re: pgcheck - data integrity check

I'm a little confused.  I assumed that your project would check the pages of a 
*shut-down* database or one in recovery (single-user) mode as part of 
recovery after a crash or HW failure.  We don't really want users running the 
database in normal mode if there's any significant chance of data-page 
corruption.

Can you back up and explain what you're trying to accomplish with this tool?
