构建postgis 2.0.0失败

Question

我在archlinux上安装了postgresql 9.3。

我正在尝试还原使用postgis 2.0函数、类型等的数据库备份(psql <db_hame> < backup.file)。我尝试安装postgis与pacman (pacman -S postgis)一起成功安装，但似乎2.0和2.1版本是不兼容的，因为在数据库导入过程中有很多错误抱怨缺少函数：

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:  could not find function "geometry_analyze_2d" in file "/usr/lib/postgresql/postgis-2.1.so"

ERROR:  could not find function "geometry_gist_sel_2d" in file "/usr/lib/postgresql/postgis-2.1.so"
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，生成失败，有以下错误：

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

和整个makepkg日志：http://pastebin.com/GGqECymZ

如何导入使用postgis 2.0的数据库？

Answer 1

嗯，要让它起作用是很有挑战性的。

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postgres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 (它本身就是github：https://github.com/philbns/PostGIS-2.0-PKGBUILD上的包)。

另一个问题是postgres包裹。我尝试了9.1.4，但是它失败了db初始化，有一些错误。最后，我找到了能够初始化db的9.1.10。没有postgres 9.1.10包，所以我使用postgres 9.1.4包(来自https://projects.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/postgresql&id=5bd2e474704f619449287efc7310acebcaf15ab4)，然后将pkgver改为9.1.10祈祷，希望一切顺利。这起作用了！我建造了postgres，然后postgis安装了它们。

我在我的db中启用了postgis扩展名：

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

最后，导入我的db备份，没有任何错误。
