I think it should be ColId.

Certainly not -- shouldn't they come from a catalog? In that case, it
must come in parse analysis (parser/analyze.c I guess) or perhaps later,
when you actually execute the function to create the new collation.

Why does a collation have a schema?
What's the "existing collation"?
It seems a bit silly to have enum for what are basically boolean
variables. Why not just use "true" and "false"?
