I am running postgresql-9.5.3 and I tried to create extension:
CREATE EXTENSION IF NOT EXISTS hstore;
but I got this error:
could not open extension control file "/usr/share/pgsql/extension/hstore.control": No such file or directory
How can I install hstore?
The package providing additional modules must be installed in your system.
For Fedora:
yum install postgresql-contrib
Or (for plain users):
sudo yum install postgresql-contrib
