This patch added this documentation text: + Replies are only sent when WAL is written to disk, so setting + <varname>fsync</> to <literal>off</> on the standby will significantly + reduce performance of synchronous replication and should be avoided. Should we also issue a warning message in the server logs for the use of fsync=off on the standby? -- Bruce Momjian <br...@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. + -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
