Обсуждение: Accessing RelOptInfo structure from the executor module

 Hello,

 I am trying to work with the Postgresql-7.3.4 and can you
 please help me with it.
 I have the following problem:
 I want to access the RelOptInfo data structure from the executor module.
 Basically I have added a flag to the RelOptInfo data structure and at
the
 time of execution I want to check the flag but I got lost after the path
 selection. I am unable to access  the RelOptInfo in the execution
module.

 Can you please help me out with this.

 Your help will be appreciated,

 Sincerely,

You can't, because it doesn't exist any more.  RelOptInfo is a planner
internal data structure, and is probably pfree'd before the executor starts.

Perhaps you could explain your problem at a higher level?
