I tried Arch and it's not the case, my examples:
PostgreSQL: https://www.postgresql.org/docs/9.6/static/release-9-6-2.htm... 9.6.2 released 2017-02-09, in Arch repos - https://git.archlinux.org/svntogit/packages.git/log/trunk?h=... - almost a MONTH later. 9.6 released 2016-09-29, in Arch repos - 2016-10-29 (version 9.6.1, they skipped 9.6) - again, a MONTH later.
Had issues with outdated Node.js and some other package I can't recall.
To be honest, up to date packages for me were only available with brew in macOS.
