Hello Kyotaro-san, I see this patch is stuck in WoA since 2019/12/01, although there's a new patch version from 2020/01/14. But the patch seems to no longer apply, at least according to https://commitfest.cputube.org :-( So at this point the status is actually correct.
Not sure about the appveyor build (it seems to be about jsonb_set_lax), but on travis it fails like this: catcache.c:820:1: error: no previous prototype for ‘CatalogCacheFlushCatalog2’ [-Werror=missing-prototypes] so I'll leave it in WoA for now. regards -- Tomas Vondra http://www.2ndQuadrant.com PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
