I'd like to start doing that by moving the functions in the following
heapam.h block elsewhere:

/* in heap/heapam.c */
extern Relation relation_open(Oid relationId, LOCKMODE lockmode);
extern Relation try_relation_open(Oid relationId, LOCKMODE lockmode);
extern Relation relation_openrv(const RangeVar *relation, LOCKMODE lockmode);
extern Relation relation_openrv_extended(const RangeVar *relation,
                                                 LOCKMODE lockmode, bool missing_ok);
extern void relation_close(Relation relation, LOCKMODE lockmode);

extern Relation heap_open(Oid relationId, LOCKMODE lockmode);
extern Relation heap_openrv(const RangeVar *relation, LOCKMODE lockmode);
extern Relation heap_openrv_extended(const RangeVar *relation,
                                         LOCKMODE lockmode, bool missing_ok);

ISTM that the first block would best belong into new files like
access/rel[ation].h and access/common/rel[ation].h.  I think the second
set should be renamed to be table_open() (with backward compat
redirects, there's way way too many references) and should go into
access/table.h access/table/table.c alongside tableam.[ch], but I could
also see just putting them into relation.[ch].
