Disable CREATE VIEW ON stmt with PIVOT operator due to pg_dump cannot dump pivot view with correct dependency and newly added fields in FuncExpr casued readFunc failed to parse previous minor version string parsetree during select from view after mVU.

There was a problem hiding this comment.
fmgr.h is a header file used by execSRF.c. And List hasn't been used in execSRF.c until we added our pivot logic. So we need to include this to fmgr.h

…resql#299) This commit fixed an issue that CTE and JOIN cannot be used with pivot operator. We added 1 field (Node *context) in FuncExpr Struct to store pivot additional information. FuncExpr will carry the pivot information to ExecMakeTableFunctionResult. In this function, we pass the pivot information into two newly added FunctionCallInfo that we can retrieve at bbf_pivot function.

Description
This commit fixed an issue that CTE and JOIN cannot be used with pivot operator.
We added 1 field (
Node *context) in FuncExpr Struct to store pivot additional information. FuncExpr will carry the pivot information to ExecMakeTableFunctionResult. In this function, we pass the pivot information into two newly added FunctionCallInfo that we can retrieve at bbf_pivot function.Issues Resolved
