构建

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

pig build pkg pg_polyline         # 构建 RPM / DEB 包

安装

您可以直接安装 pg_polyline 扩展包的预置二进制包,首先确保 PGDGPIGSTY 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:

pig install pg_polyline;          # 当前活跃 PG 版本安装
pig ext install -y pg_polyline -v 18  # PG 18
pig ext install -y pg_polyline -v 17  # PG 17
pig ext install -y pg_polyline -v 16  # PG 16
pig ext install -y pg_polyline -v 15  # PG 15
pig ext install -y pg_polyline -v 14  # PG 14
dnf install -y pg_polyline_18       # PG 18
dnf install -y pg_polyline_17       # PG 17
dnf install -y pg_polyline_16       # PG 16
dnf install -y pg_polyline_15       # PG 15
dnf install -y pg_polyline_14       # PG 14
apt install -y postgresql-18-pg-polyline   # PG 18
apt install -y postgresql-17-pg-polyline   # PG 17

创建扩展

CREATE EXTENSION pg_polyline;

用法

pg_polyline: PostgreSQL 的 Google 编码折线编解码

快速的 Google 编码折线编码与解码 PostgreSQL 扩展。基于 pgrx 构建。

CREATE EXTENSION pg_polyline;

-- 将点数组编码为折线字符串
SELECT polyline_encode(
  ARRAY[point(-120.2, 38.5), point(-120.95, 40.7), point(-126.453, 43.252)], 6
);
--          polyline_encode
-- ----------------------------------
--  _izlhA~rlgdF_{geC~ywl@_kwzCn`{nI

-- 将折线字符串解码回点数组
SELECT polyline_decode('_ibE_seK_seK_seK', 6);
--       polyline_decode
-- ---------------------------
--  {"(0.2,0.1)","(0.4,0.3)"}

第二个参数是精度(小数位数)。
