Thanks for working on this refactor. LGTM! I had a few minor comments:
1. We should rename the CopyFormatOptions *cstate param in
ProcessCopyOptions() to CopyFormatOptions *options and List *options to
List *raw_options IMO, to make it more readable.
2. We need to update the header comment for Copy{From,To}StateData. It is
currently the old comment from CopyStateData.
3. Can we add docs for the missing fields in the header comment for
BeginCopyFrom()?

Comment needs to be updated for the COPY operation.

Would we be better off if we sub-struct CopyState <- Copy{From,To}State?
Like this:
typedef struct Copy{From|To}StateData
{
CopyState cs;
// Fields specific to COPY FROM/TO follow..
}

Can we replace this if with an else?
