Question

我在archlinux上安装了postgresql 9.3。

我正在尝试恢复使用postgis 2.0函数，类型等的数据库备份（psql <db_hame> < backup.file）。我尝试使用pacman（pacman -S postgis）安装postgis，但是它成功安装了{{1} }}和2.0版本不兼容，因为我有很多错误抱怨数据库导入过程中缺少函数：

2.1

然后我尝试使用以下链接构建postgis包：http://boringnerdystuff.wordpress.com/2012/04/14/postgis-2-0-pkgbuild-for-arch-linux/和https://github.com/philbns/PostGIS-2.0-PKGBUILD/tree/80d8af061fa73e9a09dd6ec5c204bc4b65e38202。但是，构建失败并出现以下错误：

如何导入使用postgis 2.0的数据库？

Answer 1

嗯，要让它发挥作用是非常具有挑战性的。

我无法针对postgres 9.3构建postgis 2.0.0，所以我不得不回滚到postgres 9.1.10并从源代码构建postgress和postgis。

我使用指令从http://boringnerdystuff.wordpress.com/2012/04/14/postgis-2-0-pkgbuild-for-arch-linux/构建postgis（本身包在github上：https://github.com/philbns/PostGIS-2.0-PKGBUILD）。

另一个问题是postgres包。我尝试了9.1.4，但是数据库初始化失败并出现了一些错误。最后我发现9.1.10可以初始化db。 postgres 9.1.10没有包，所以我使用了postgres 9.1.4的包（来自https://projects.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/postgresql&id=5bd2e474704f619449287efc7310acebcaf15ab4），然后将pkgver更改为9.1.10交叉手指，希望一切顺利。这很有效！我建了postgres然后postgis并安装它们。

我在我的数据库中启用了postgis扩展名：

CREATE EXTENSION postgis;
CREATE EXTENSION postgis_topology;
CREATE EXTENSION fuzzystrmatch;

最后我的数据库备份导入没有任何错误。
