构建

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

BASH

pig build pkg pg_bzip         # 构建 RPM / DEB 包

安装

您可以直接安装 pg_bzip 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：

BASH

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

BASH

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

pig

BASH

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

dnf

BASH

dnf install -y pg_bzip_18       # PG 18
dnf install -y pg_bzip_17       # PG 17
dnf install -y pg_bzip_16       # PG 16
dnf install -y pg_bzip_15       # PG 15
dnf install -y pg_bzip_14       # PG 14

apt

BASH

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

创建扩展：

SQL

CREATE EXTENSION bzip;

用法

bzip: Bzip 压缩与解压缩

函数

bzcat(data bytea) returns bytea – 解压 bzip2 数据，类似于 bzcat 命令。
bzip2(data bytea, compression_level int default 9) returns bytea – 使用 bzip2 压缩数据。

示例

解压 bzip2 压缩的文件：

SQL

SELECT convert_from(bzcat(pg_read_binary_file('/path/to/data.csv.bz2')), 'utf8') AS contents;

使用 bzip2 压缩数据：

SQL

SELECT bzip2(repeat('my text to be compressed', 1000)::bytea) AS compressed;

使用自定义压缩级别（1-9）进行压缩：

SQL

SELECT bzip2('some data'::bytea, 5);
