I’m trying to install Postgis 2.0 on a perfectly functionig postgresql 9.1.10 database.
I installed the package via:
richard@srv1:/$ sudo apt-get install postgresql-9.1-postgis postgis
Reading package lists... Done
Building dependency tree
Reading state information... Done
postgis is already the newest version.
postgresql-9.1-postgis is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.
With out any errors.
Then I try to add postgis as an extension to an existing (empty) database, with:
dev=# CREATE EXTENSION postgis;
ERROR: could not open extension control file "/usr/share/postgresql/9.1/extension/postgis.control": No such file or directory
If I look at the location the file does not exist.
What am I missing? I can’t figure it out. If I google I only get ancient results….
Where can I find the version of the installed postgis? As I’m not able to do a SELECT PostGIS_version();
Environment: Postgresql 9.1.10, Ubuntu 12.04
Update
I’m willing to install postgis2.0; apparently I have 1.5 installed. After purging that version I added the repository
deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main
After trying to install the package via
sudo apt-get update
sudo apt-get install postgis
it ends with:
Errors were encountered while processing:
/var/cache/apt/archives/libgdal1_1.9.0-3.1~pgdg12.4+1_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
Update 2
It appears because of the naming of the packages, it installed the wrong architecture type package.
But I ended up using this website and these steps after making sure I had gdal>= 1.9.0 and GEOS >=3.3.3:
wget http://postgis.refractions.net/download/postgis-2.0.0.tar.gz
tar xfvz postgis-2.0.0.tar.gz
cd postgis-2.0.0
./configure --with-gui
make
sudo make install
sudo ldconfig
sudo make comments-install
sudo ln -sf /usr/share/postgresql-common/pg_wrapper /usr/local/bin/shp2pgsql
sudo ln -sf /usr/share/postgresql-common/pg_wrapper /usr/local/bin/pgsql2shp
sudo ln -sf /usr/share/postgresql-common/pg_wrapper /usr/local/bin/raster2pgsql
