Move have_partkey_equi_join and match_expr_to_partition_keys to relnode.c, since they're used only there. Refactor build_joinrel_partition_info to split out the code that fills the joinrel's partition key lists; this doesn't have any non-cosmetic impact, but it seems like a useful separation of concerns. Improve assorted nearby comments. Amit Langote, with a little further editorialization by me Discussion: https://postgr.es/m/CA+HiwqG2WVUGmLJqtR0tPFhniO=H=9qQ+Z3L_ZC+Y3-EVQHFGg@mail.gmail.com
