+
+ Fix rare failure to invalidate relation cache init file (Tom Lane)
+
+
+
+ With just the wrong timing of concurrent activity, a VACUUM
+ FULL on a system catalog might fail to update the init file
+ that's used to avoid cache-loading work for new sessions. This would
+ result in later sessions being unable to access that catalog at all.
+ This is a very ancient bug, but it's so hard to trigger that no
+ reproducible case had been seen until recently.
+
+
+
+
+
+ Avoid deadlock between incoming sessions and CREATE/DROP
+ DATABASE (Tom Lane)
+
+
+
+ A new session starting in a database that is the target of
+ a DROP DATABASE command, or is the template for
+ a CREATE DATABASE command, could cause the command to wait
+ for five seconds and then fail, even if the new session would have
+ exited before that.
