Before compilation, we grab an exclusive lock and attempt a final cache lookup just to be sure that a compiled plan has not been inserted while we were waiting to acquire the compile lock. If this too fails, we do a full compile, insert a new compiled plan and release the compile lock...
逻辑备份cache lookup failed错误分析 除了考虑数据的一致性备份,还需要考虑结构的一致性。 某些获取数据结构的调用是snapshot now的,所以可能有很小的窗口期可能被执行DDL,从而导致relcache变化。 如果pg_dump发现relcache变化,则会爆出cache lookup failed的错误,导致备份失败。
