Re: [HACKERS] Rule plan size for views?

darrenk

So when I do it as a select statement the plan can grow larger than 8K 
because I can run the SQL command itself.

Has the plan generation changed in the last week?  I was able to create 
another view in an earlier beta but cannot now.

Is there a way to find out the size of the plan?
