So, I was trying to install extension citext on PostrgeSQL 11.1, but of course I've encountered an error:

ERROR:  could not open extension control file "/usr/pgsql-11/share/extension/citext.control": No such file or directory

I ran sudo yum install postgresql-contrib , but dependency for version 9.2 was installed. So where to find and how to install citext on PostgreSQL 11.1 on CentOS 7.6 ?

Thank you!


First make sure you have the correct rpm files installed for postgres 11. Then run

sudo yum install postgresql11-contrib

Here is a good article for installing postgresql on centos7
