Hi,
Thanks for your comments.
I updated the patch to v2.
* Update a comment instead writing documentation about
the wait events for pg_prewarm.
* Make the name of wait events which are different code
path different. Add DblinkGetConnect and PgPrewarmDumpShutdown.
* Make variable names shorter like pgfdw_we_receive.
* Update documents.
* Add some tests with pg_wait_events view.
Regards,
