构建 postgis 2.0.0 失败

Question

我在 archlinux 上安装了 postgresql 9.3。

我正在尝试恢复使用 postgis 2.0 功能、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，它已成功安装，但似乎 2.0 和 2.1版本不兼容，因为我有很多错误抱怨在数据库导入期间缺少功能：

ERROR:  could not find function "geography_analyze" in file "/usr/lib/postgresql/postgis-2.1.so"
ERROR:  function public.geography_analyze(internal) does not exist
ERROR:  function geography_analyze(internal) does not exist

ERROR:  function public.geometry_gist_sel_2d(internal, oid, internal, integer) does not exist

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：

lwgeom_triggers.c: In function ‘cache_bbox’:
lwgeom_triggers.c:78:33: error: dereferencing pointer to incomplete type
  tupdesc = trigdata->tg_relation->rd_att;

如何导入使用 postgis 2.0 的数据库？

Answer 1

嗯，让它工作起来非常具有挑战性。

我无法针对 postgres 9.3 构建 postgis 2.0.0，因此我不得不回滚到 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（它的包在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，但它未能通过一些错误初始化数据库。最后我找到了可以初始化db的9.1.10。 postgres 9.1.10 没有包，所以我使用了 postgres 9.1.4 的包（从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，希望一切都好。这奏效了！我构建了 postgres 然后 postgis 并安装了它们。

我在我的数据库中启用了 postgis 扩展：

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。
