提问by Oleg
I have tried to install pg_dumpas part of installation of postgres-client, however it does not include pg_dump.
我尝试将安装pg_dump作为 安装的一部分postgres-client，但它不包括pg_dump.
Can pg_dumpbe installed without a full installation of postgres on Alpine Linux?
可以pg_dump在 Alpine Linux 上不完整安装 postgres 的情况下安装吗？
回答by Lee Benson
No - to install pg_dumpand associated utilities, you'll need to run apk add postgresql, which will install the full PostgreSQL suite.
否 - 要安装pg_dump和关联实用程序，您需要运行apk add postgresql，这将安装完整的 PostgreSQL 套件。
The installed size is currently 12.1mb (for v9.6.0-r1) vs just 451kb for postgresql-client, so it's definitely bigger. If you're using Alpine in Docker, that might not be a big deal. If you're using it in an embedded device where size matters, you could simply copy over pg_dumpor whatever else you need.
安装的大小目前是 12.1mb（对于 v9.6.0-r1），而对于 451kb postgresql-client，所以它肯定更大。如果您在 Docker 中使用 Alpine，那可能没什么大不了的。如果您在尺寸很重要的嵌入式设备中使用它，您可以简单地复制pg_dump或任何您需要的东西。
