Hi all, ALTER SYSTEM currently does not raise error upon invalid entry. Take for example:
alter system set superuser_reserved_connections = 10; > ALTER SYSTEM alter system set max_connections = 5; > ALTER SYSTEM The database will now fail to restart without manual intervention by way of editing the autoconf file (which says "# Do not edit this file manually!" on its first line). The attached WIP patch is intended to raise an error on invalid ALTER SYSTEM commands before being written out to the filesystem. Hopefully this behavior is more intuitive.
