Ah nuts, yes it's supposed to be supported, we seem to not initialize
cstate->range_table in tablesync which causes this bug. The CopyState
struct is private to copy.c so we can't easily set cstate->range_table
externally. I wonder if tablesync should just construct CopyStmt instead
of calling the lower level API.
