扩展安装

使用 pig 命令行工具安装 pg_wait_sampling 扩展:

pig ext install pg_wait_sampling

使用 Pigsty剧本 安装 pg_wait_sampling 扩展:

./pgsql.yml -t pg_extension -e '{"pg_extensions": ["pg_wait_sampling"]}' # -l <集群名>

YUM仓库 手工安装 pg_wait_sampling RPM 包:

dnf install pg_wait_sampling_17*;
dnf install pg_wait_sampling_16*;
dnf install pg_wait_sampling_15*;
dnf install pg_wait_sampling_14*;
dnf install pg_wait_sampling_13*;

APT仓库 手工安装 pg_wait_sampling DEB 包:

apt install postgresql-17-pg-wait-sampling;
apt install postgresql-16-pg-wait-sampling;
apt install postgresql-15-pg-wait-sampling;
apt install postgresql-14-pg-wait-sampling;
apt install postgresql-13-pg-wait-sampling;

扩展 pg_wait_sampling 需要通过 shared_preload_libraries 进行 动态加载

shared_preload_libraries = 'pg_wait_sampling'; # 修改 PG 集群配置

使用以下 SQL 命令在已经安装此扩展插件的 PG 集群上 启用 pg_wait_sampling 扩展:

CREATE EXTENSION pg_wait_sampling;
