operating-system/buildroot/package/timescaledb/0004-Add-support-for-PG13-List-implementation.patch
Stefan Agner f358f322da Bump Buildroot to 2021.02-rc3 (#1260) 
* Rebase patches to Buildroot 2021.02-rc3

* Update Buildroot to 2021.02-rc3

* Declare Kernel headers to be Linux version 5.10 (since they are, and new Buildroot knows about 5.10)

Raw Blame History

From 259ff80eb29c2c70e6afb77d266ce49cccbef223 Mon Sep 17 00:00:00 2001
From: Sven Klemm <sven@timescale.com>
Date: Sat, 19 Sep 2020 22:20:34 +0200
Subject: [PATCH] Add support for PG13 List implementation
PG13 changes the List implementation from a linked list to an array
while most of the API functions did not change a few them have slightly
different signature in PG13, additionally the list_make5 functions
got removed.
