RelationPurgeLocalRelation():
 /* * RelationFlushRelation () below will flush relation information * from the cache. We must call smgrclose to flush relation * information from SMGR & FMGR, too. We assume that for temp * relations smgrunlink is already called by heap_destroyr * and we skip smgrclose for them. - vadim 05/22/97 */ smgrclose(reln->rd_rel->relsmgr, reln); - it avoids memory leaks in SMGR & VFD.RelationFlushRelation(): there is no more call FileInvalidate(RelationGetSystemPort(relation)); - invalid (FileInvalidate() expects File, not SMGR' fd) - unuseful anyway.
