I'm not following here. heap_inplace_update() indeed writes WAL, but it does *NOT* (and may not) assign an xid. Thus we're not emitting the relcache invalidation queued in DefineIndex(), as RecordTransactionCommit() currently skips emitting a commit record if there's no xid. > So I'm not seeing this as an extant bug in an open source version of > PostgreSQL, in my current understanding. But the first message in the thread demonstrated a reproducible problem?
