In branches before 17, this commit is causing some compilers
to complain:
index.c: In function 'index_update_stats':
index.c:2913:24: warning: 'relpages' may be used uninitialized in this function [-Wmaybe-uninitialized]
if (rd_rel->relpages != (int32) relpages)
~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~
I'm seeing that with RHEL8's gcc 8.5.0, and trawling the buildfarm
shows at least 40 animals similarly unhappy. (I noticed this because
mamba, which is using -Werror, is actually failing.)
