Hi,
In postgres_fdw, pgfdw_xact_callback() and pgfdw_subxact_callback() do
almost the same thing to rollback remote toplevel- and sub-transaction.
But their such rollback logics are implemented separately and
in different way. Which would decrease the readability and maintainability,
I think. So how about making the common function so that those callback
functions can just use it? Patch attached.
Regards,
