53000
速览 {#at-a-glance}
53000 是宽泛的资源不足条件。固定调用者包括后台 worker 启动、本地缓冲区耗尽和文件描述符限制，因此必须结合消息和启动/运行阶段确定资源。
含义 {#meaning}
类别码本身不指向某个参数：could not register background process 指向 worker 容量，no empty local buffer available 指向本地缓冲区，文件描述符变体则分别报告启动最小值或进程分配上限。
诊断 {#diagnosis}
记录 primary、detail/hint、阶段和服务器日志。启动失败时比较进程限制与 worker 配置；运行中则先判断是本地缓冲区、描述符、worker 槽位还是其他固定资源。
处理 {#response}
按消息指出的资源在平台和 PostgreSQL 限制内释放或调整，清理不用的描述符/worker 后验证配置。显式事务中若发生 ERROR，重试前执行 ROLLBACK 或 ROLLBACK TO SAVEPOINT；自动提交只有在指定资源可用后才能重试。服务器进程描述符检查等启动 FATAL 路径没有客户端事务可恢复。未定位资源前不要泛化为重启或改内存。
版本 {#versions}
锁定目录从 7.4 记录；引用调用者来自 PostgreSQL 18.6 源码，未在主机制造资源耗尽。
