构建
您可以使用 pig build 命令构建 pg_convert 扩展的 RPM / DEB 包：
pig build pkg pg_convert # 构建 RPM / DEB 包
安装
您可以直接安装 pg_convert 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：
pig install pg_convert; # 当前活跃 PG 版本安装
pig ext install -y pg_convert -v 18 # PG 18
pig ext install -y pg_convert -v 17 # PG 17
pig ext install -y pg_convert -v 16 # PG 16
pig ext install -y pg_convert -v 15 # PG 15
pig ext install -y pg_convert -v 14 # PG 14
dnf install -y pg_convert_18 # PG 18
dnf install -y pg_convert_17 # PG 17
dnf install -y pg_convert_16 # PG 16
dnf install -y pg_convert_15 # PG 15
dnf install -y pg_convert_14 # PG 14
apt install -y postgresql-18-convert # PG 18
apt install -y postgresql-17-convert # PG 17
apt install -y postgresql-16-convert # PG 16
apt install -y postgresql-15-convert # PG 15
apt install -y postgresql-14-convert # PG 14
创建扩展：
CREATE EXTENSION convert;
