Extend compatibility of PostgreSQL::Test::Cluster
Andrew Dunstan <andrew@dunslane.net> — 2021-12-28T14:30:24Z
PFA a patch to extend the compatibility of PostgreSQL::Test::Cluster to all live branches. It does this by introducing a couple of subclasses which override a few things. The required class is automatically detected and used, so users don't need to specify a subclass. Although this is my work it draws some inspiration from work by Jehan-Guillaume de Rorthais. The aim here is to provide minimal disruption to the mainline code, and also to have very small override subroutines. My hope is to take this further, down to 9.2, which we recently decided to give limited build support to. However I think the present patch is a good stake to put into the ground. cheers andrew -- Andrew Dunstan EDB: https://www.enterprisedb.com

This version handles older versions for which we have no subclass more gracefully. cheers andrew -- Andrew Dunstan EDB: https://www.enterprisedb.com

It was always my intention to commit it this time, and I propose to do so tomorrow with the comment Michael has requested above.
