There's been a massive addition of partitioning code in PostgreSQL 11, with little oversight on its placement, resulting in a catalog/partition.c with poorly defined boundaries and responsibilities. This commit tries to set a couple of distinct modules to separate things a little bit. There are no code changes here, only code movement. There are three new files: src/backend/utils/cache/partcache.c src/include/partitioning/partdefs.h src/include/utils/partcache.h The previous arrangement of #including catalog/partition.h almost everywhere is no more.
