Hmm. The "unlogged" record is written here: ... void heap_sync(Relation rel) { char reason[NAMEDATALEN + 30]; /* temp tables never need fsync */ if (rel->rd_istemp) return; snprintf(reason, sizeof(reason), "heap inserts on \"%s\"", RelationGetRelationName(rel)); XLogReportUnloggedStatement(reason); ... So it clearly shouldn't be written for temp relations. Apparently the rd_istemp flag not set correctly after CLUSTER / VACUUM FULL.
