Please note that the patch has a warning, causing cfbot-san to
complain:
catcache.c:786:1: error: no previous prototype for
‘CatalogCacheFlushCatalog2’ [-Werror=missing-prototypes]
 CatalogCacheFlushCatalog2(Oid catId)
 ^
cc1: all warnings being treated as errors

So this should at least be fixed.  For now I have moved it to next CF,
waiting on author.
