构建

您可以使用 pig build 命令构建 pgmeminfo 扩展的 RPM / DEB 包：

pig build pkg pgmeminfo         # 构建 RPM / DEB 包

安装

您可以直接安装 pgmeminfo 扩展包的预置二进制包，首先确保 PGDG 和 PIGSTY 仓库已经添加并启用：

pig repo add pgsql -u          # 添加仓库并更新缓存

使用 pig 或者是 apt/yum/dnf 安装扩展：

安装

pig install pgmeminfo;          # 当前活跃 PG 版本安装

pig

pig ext install -y pgmeminfo -v 18  # PG 18
pig ext install -y pgmeminfo -v 17  # PG 17
pig ext install -y pgmeminfo -v 16  # PG 16
pig ext install -y pgmeminfo -v 15  # PG 15
pig ext install -y pgmeminfo -v 14  # PG 14

dnf

dnf install -y pgmeminfo_18       # PG 18
dnf install -y pgmeminfo_17       # PG 17
dnf install -y pgmeminfo_16       # PG 16
dnf install -y pgmeminfo_15       # PG 15
dnf install -y pgmeminfo_14       # PG 14

apt

apt install -y postgresql-18-pgmeminfo   # PG 18
apt install -y postgresql-17-pgmeminfo   # PG 17
apt install -y postgresql-16-pgmeminfo   # PG 16
apt install -y postgresql-15-pgmeminfo   # PG 15
apt install -y postgresql-14-pgmeminfo   # PG 14

创建扩展：

CREATE EXTENSION pgmeminfo;

用法

来源：

pgmeminfo 报告当前 PostgreSQL 后端的内存分配器统计及内存上下文层级，不汇总整个集群的内存。

检查内存

由超级用户安装扩展，然后检查当前连接：

CREATE EXTENSION pgmeminfo;
SELECT * FROM pgmeminfo();
SELECT * FROM pgmeminfo_contexts();
SELECT * FROM pgmeminfo_contexts(deep => 1);
SELECT * FROM pgmeminfo_contexts(deep => -1, accum_mode => 'off');

pgmeminfo() 返回 arena、uordblks、fordblks、keepcost 等分配器计数。这些指标与内存分配器相关，不是进程 RSS，也不能用于估算集群空闲内存。

pgmeminfo_contexts(deep, accum_mode) 返回上下文名称、父节点、层级和字节计数。默认累积模式为 all；off 不累加后代上下文，deep => -1 取消层级深度限制。

运行与版本

不需要预加载或重启。上游发布版本 1.0.1 保持 SQL 扩展版本 1.0；不要把安装包版本 1.0.1 用作 SQL 升级目标。后端执行查询时，上下文名称和统计值可能变化。如果不希望普通用户查看内部上下文名称，应检查函数访问权限。
