如何使用正确的PostgreSQL版本安装pgxn? [英] How to install pgxn with correct PostgreSQL version?

问题描述

在sudo -H pgxn install semver上，关于错误的PostgreSQL版本(是v10而不是v12)的错误，

INFO: best version: semver 0.20.3
INFO: saving /tmp/tmpba6hta5a/semver-0.20.3.zip

/usr/bin/install -c -m 644 .//sql/semver--0.20.0.sql ...

我也尝试通过此线索使用sudo apt install postgresql-server-dev-10修复"postgresql标头"，但没有效果./p>

我正在使用 pgxn.org 扩展名，该扩展名没有明显的安装指南".似乎该指南是 pgxn.github.io/pgxnclient ，但它并没有说明更改PostgreSQL配置(但有关extend-pgxs的PG指南也许可以说些什么)./p>

有关 json_fdw/issues 和解决方案

安装正常，警告是有关semver中的代码错误.

该扩展名是在您的计算机上与PostgreSQL v12安装一起构建和安装的，因为在PATH上找到的pg_config是v12中的扩展名.如果要使用v10构建和安装扩展，请确保v10中的pg_config首先 在PATH上.

On sudo -H pgxn install semver, ERROR about wrong PostgreSQL version (it is v10 not v12),

I try also to fix "postgresql headers", by this clue using sudo apt install postgresql-server-dev-10, but no effect.

I was using the pgxn.org extensions, that has no obvious "installation Guide" on its home. Seems that the Guide is pgxn.github.io/pgxnclient, but it say nothing about change PostgreSQL configs (but Pg Guide about extend-pgxs perhaps say something).

ENV details

• on psql "postgres://postgres:passwd@localhost/myBase" -c "select version()" = PostgreSQL 10.12

• old server UBUNTU 16 LTS

• psql --version = 12.2 (but SQL is 10.12!)

• pgxn installed by sudo easy_install pgxnclient.
  redo by sudo -H pip install --upgrade pgxnclient
pgxn --version = pgxnclient 1.3

• for json_fdw package prepared, before pgxn install, with sucess sudo apt install zlib1g-dev libyajl-dev.

Seems the real problem is a PostgreSQL version confusion: the two exists, ls /usr/share/postgresql/10/extension and ls /usr/share/postgresql/12/extension

解决方案

The installation worked fine, the warning is about a code bug in semver.

The extension is built and installed with the PostgreSQL v12 installation on your machine, because the pg_config found on the PATH is the one from v12. If you want to build and install the extension with v10, make sure the pg_config from v10 is first on the PATH.
