From acab1b0914e426d28789731f50f5964dd4d2f054 Mon Sep 17 00:00:00 2001 From: Andres Freund Date: Wed, 5 Apr 2023 18:57:29 -0700 Subject: Convert many uses of ReadBuffer[Extended](P_NEW) to ExtendBufferedRel() A few places are not converted. Some because they are tackled in later commits (e.g. hio.c, xlogutils.c), some because they are more complicated (e.g. brin_pageops.c). Having a few users of ReadBuffer(P_NEW) is good anyway, to ensure the backward compat path stays working.
