Right, and that is all exactly per distro recommendations, at least for Red Hat, and I'm pretty sure other distros too. This has not been changed recently TTBOMK. See for example http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html The only argument that particular document offers for including the minor number is that it makes it easier to see which specific version you have installed. That's not much, but it's not nothing either. There might be other reasons I'm not remembering. Also, SO_MINOR_VERSION is included in the shlib name for most Unix-oid platforms, not just Linux. Even if we were to conclude this was no longer recommended practice for Linux, I doubt we should unilaterally drop the practice everywhere. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
