无法在 Postgresql 上安装扩展

Can't install extension on Postgresql

我尝试在我的 Postgresql 12 上安装 semver。我成功安装了 postgis 并使用以下命令在我的 Centos 7 服务器上安装 pg-semver(semver 扩展):

yum install pg-semver

那我运行

CREATE EXTENSION semver;

我收到以下错误:

couldn't open extension control file /usr/pgsql-12/share/extension/semver.control : No such file or directory

我将所有文件从“/usr/share/pgsql/extension/”复制到“/usr/pgsql-12/share/extension”。现在我收到以下错误:

ERROR: ERROR: could not access file "semver": No such file or directory

更新(2020 年 2 月 28 日):

我删除了 pg-semver,因为它为 PSQL 9.2 提供。我现在尝试使用开发人员提供的文档来构建自己。

我从 https://github.com/theory/pg-semver/archive/master.zip 下载了 semver 扩展,然后解压。之后我 运行 以下命令:

make

并得到:

make: There is nothing to do for the "all" target. then:

make install

并得到:

/bin/sh /usr/lib64/pgsql/pgxs/src/makefiles/../../config/install-sh -c -m 644 ./semver.control '/usr/share/pgsql/extension/' /bin/sh /usr/lib64/pgsql/pgxs/src/makefiles/../../config/install-sh -c -m 644 ./sql/semver--0.20.0.sql ./sql/semver--unpackaged--0.2.1.sql ./sql/semver--0.20.0--0.21.0.sql ./sql/semver--0.12.0--0.13.0.sql ./sql/semver--0.3.0--0.4.0.sql ./sql/semver--0.16.0--0.17.0.sql ./sql/semver--0.13.0--0.15.0.sql ./sql/semver--0.11.0--0.12.0.sql ./sql/semver--0.2.4--0.3.0.sql ./sql/semver--0.2.1--0.2.4.sql ./sql/semver--0.5.0--0.10.0.sql ./sql/semver--0.10.0--0.11.0.sql ./sql/semver.sql ./sql/semver--0.17.0--0.20.0.sql ./sql/semver--0.15.0--0.16.0.sql '/usr/share/pgsql/extension/' /bin/sh /usr/lib64/pgsql/pgxs/src/makefiles/../../config/install-sh -c -m 755 src/semver.so '/usr/lib64/pgsql/' /bin/sh /usr/lib64/pgsql/pgxs/src/makefiles/../../config/install-sh -c -m 644 ./doc/semver.mmd '/usr/share/doc/pgsql/extension/'

然后:

make installcheck

并得到:

The differences that caused some tests to fail can be viewed in the file "/tmp/ttt/pg-semver-master/regression.diffs". A copy of the test summary that you see above is saved in the file "/tmp/ttt/pg-semver-master/regression.out".

/usr/pgsql-12/lib/里没有semver.so,/usr/lib64/pgsql/里有semver.so,但也是9.2版的?

按照本指南安装 semver:

https://pgxn.org/dist/semver/

无法安装semver的原因有两个:

您收到错误 could not access file "semver": No such file or directory,因为您没有将 /usr/lib64/pgsql/semver.so 复制到 /usr/pgsql-12/lib。但是,由于以下第二个原因,您不能简单地复制它:

yum install pg-semver 将从 EPEL 库安装 semver,它是 CentOS 7 附带的预打包的 PostgreSQL 版本 9.2。您安装了 PostgreSQL 版本 12(通过自己编译或下载 PGDG 存储库并安装 postgresql12 包)。 EPEL 存储库附带的 semver.so 文件不兼容,因为它是针对 PostgreSQL 版本 9.2 而不是版本 12 编译的。如果您尝试将 EPEL semver.so 加载到您的 v.12 数据库中,你会看到:

postgres=# create extension semver;
ERROR:  incompatible library "/usr/pgsql-12/lib/semver.so": version mismatch
DETAIL:  Server is version 12, library is version 9.2.

因此,您安装semver的唯一方法是按照编译步骤detailed in the documentation:

make
make install
make installcheck
psql -c "CREATE EXTENSION semver;"

如果您还没有这样做(并且您通过 PGDG RPM 安装了 postgresql 12),则需要执行以下操作才能下载和编译:

yum -y install postgresql12-devel
yum -y groupinstall "Development Tools"

您也可能 运行 遇到编译问题,例如:clang: error: unknown argument: '-flto=thin' 因为 PGDG RPM 是使用 clang 编译的——您可以通过以下方式绕过它:

with_llvm=no make -e
with_llvm=no make -e install
with_llvm=no make -e installcheck
psql -c "create extension semver"
