From d298b50a3b469c088bb40a4d36d38111b4cd574d Mon Sep 17 00:00:00 2001 From: Heikki Linnakangas Date: Fri, 22 Mar 2013 13:02:59 +0200 Subject: Make pg_basebackup work with pre-9.3 servers, and add server version check. A new 'starttli' field was added to the response of BASE_BACKUP command. Make pg_basebackup tolerate the case that it's missing, so that it still works with older servers. Add an explicit check for the server version, so that you get a nicer error message if you try to use it with a pre-9.1 server. The streaming protocol message format changed in 9.3, so -X stream still won't work with pre-9.3 servers. I added a version check to ReceiveXLogStream() earlier, but write that slightly differently, so that in 9.4, it will still work with a 9.3 server. (In 9.4, the error message needs to be adjusted to "9.3 or above", though). Also, if the version check fails, don't retry. --- doc/src/sgml/ref/pg_basebackup.sgml | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'doc/src') diff --git a/doc/src/sgml/ref/pg_basebackup.sgml b/doc/src/sgml/ref/pg_basebackup.sgml index 578541a1e2a..9fe440a66de 100644 --- a/doc/src/sgml/ref/pg_basebackup.sgml +++ b/doc/src/sgml/ref/pg_basebackup.sgml @@ -520,6 +520,12 @@ PostgreSQL documentation for all additional tablespaces must be identical whenever a backup is restored.
