If so, we can pgfdw_exec_pre_commit() into two, one is the common
function that sends or executes the command (i.e., calls
do_sql_command_begin() or do_sql_command()), and another is
the function only for toplevel. The latter function calls
the common function and then executes DEALLOCATE ALL things.
But this is not the way that other functions like pgfdw_abort_cleanup()
is implemented. Those functions have both codes for toplevel and
!toplevel (i.e., subxact), and run the processings depending
on the argument "toplevel". So I'm thinking that
pgfdw_exec_pre_commit() implemented in the same way is better.

Same as above.
