Hi,

I want to take a plan generated by the postgres optimizer and insert a
constant in place of another constant in the plan. There is a function
OidOutputFunctionCall() to get the constant. Similarly, is there any
function to set the value of the constant? What does
OidInputFunctionCall() do?

Please reply soon, this is an emergency..

Thanks a lot,
Shruthi
