Hi, i am trying to mutate a plan for a T_CreateTableAsStmt before it executes.
I've created a planner_hook_type hook, where i can see the plan that gets executed as part of the AS of the query,
wherethe CmdType is CMD_SELECT, and its subplans are the plans for the actual select itself.
I've also created a ProcessUtility_hook_type, which correctly shows the T_CreateTableAsStmt, but the hook is called
afterthe actual CREATE TABLE is called, and the plan is no longer mutable for the part that i need.
Is there another hook i should be looking at, or another way i should be approaching this? I need to be able to alter
theplan specifically for the SELECT portion of a CREATE TABLE AS query, but only in the case of the SELECT TABLE AS,
andin no other SELECTs.
Alternately, I can look at the query string in the CMD_SELECT planner hook and search specifically for CREATE, TABLE
andAS, but I feel that there has to be a better way, and look forward to some guidance.
Thanks!
