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
