Hi Kuroda-san,
Thank you for updating the patch!
I think we can update the status to ready for committer after
this fix, if there is no objection.

Yes, to align with the postgres_fdw_verify_connection_states()
case, how about writing the connection is not valid. Like the
following?
'NULL is returned if no valid connections are established or
this function...'
This is my comment for v35. Please check.
0002:
1. the comment of verify_cached_connections (I missed one minor point.)
+ * This function emits warnings if a disconnection is found. This
returns true
+ * if disconnections cannot be found, otherwise returns false.
I think false is returned only if disconnections are found and
true is returned in all other cases. So, modifying the description
like the following seems better.
'This returns false if disconnections are found, otherwise
returns true.'
