I've just installed Postgres 9.3.4 and PostGIS 2.1 on OSX Mavericks using the very latest versions of the KyngChaos libraries. This is a new machine, and I deliberately haven't installed Postgres using Homebrew or Macports.

However, when I try to create spatial extensions on a database, I can't, because Postgres claims not to be able to see the extension file:

:~ anna$ psql -d land -c "CREATE EXTENSION postgis;"
ERROR:  could not open extension control file 
No such file or directory

It looks as though the file is located somewhere else:

:~ anna$ mdfind postgis.control

I'm definitely using the expected version of Postgres, although I don't know it's actually the Kyngchaos version:

:~ anna$ psql --version
psql (PostgreSQL) 9.3.4

:~ anna$ which psql

It looks like perhaps there are multiple versions of Postgres floating around on my system, and I'm using the wrong one?

:~ anna$ mdfind -name "postgres" | grep -G "postgres$"

Can anyone advise me on what to do next?

  • You've definitely got at least two versions there. Where did the Cellar one come from? That seems to be the one you are using from the error note in the create extension. How did you start up your postgresql service?

  • Thanks. In the end the answer - as always with PostGIS installation questions, I find - was to uninstall all versions of Postgres / PostGIS from my machine, and start again from scratch.

You need to also install postgis-scripts as included in the following, which solved the same issue for me: StackOverflow Answer
