Обсуждение: Isn't remote_write a really dumb name for that setting?
AFAICT, the remote_write setting for synchronous_commit is named exactly
backwards, because the point of the setting is that it *doesn't* wait
for the remote to write anything.
As an alternative I suggest "remote_receive". Perhaps somebody else
has a better idea?

Yes, I didn't like remote_write either; see this thread: http://archives.postgresql.org/pgsql-hackers/2012-05/msg00375.php Yes, please, I would like it changed. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. +

After re-reading that thread (and looking at the code to be sure), I think the mode name is all right; it's the documentation that is 100% broken. The actual meaning of the setting is that we wait for the remote to write() the data, but not fsync() it. The description in the SGML docs has nothing to do with reality. Will fix the docs. regards, tom lane
