Looking at the list of Perl versions shipped with various OSes (https://www.cpan.org/ports/binaries.html), bumping the minimum requirement from 5.8.1 to 5.8.3 will affect the following OS versions, which shipped 5.8.1 or 5.8.2: AIX: 5.3, 6.1 Fedora: 1 (Yarrow) macOS: 10.3 (Panther) Redhat: 2.1 Slackware: 9.0, 9.1 OpenSUSE: 8.2 The only one of these that I can imagine we might possibly care about is AIX, but I don't know what versions we claim to support or people actually run PostgreSQL on (and want to upgrade to 15). The docs at https://www.postgresql.org/docs/current/installation-platform-notes.html just say that "AIX versions before about 6.1 […] are not recommended". For reference, 6.1 was released on 2007-11-09 and EOL on 2017-04-30, and 7.1 was released on 2010-09-10 and is supported until 2023-04-30. - ilmari
