I have installed PostgreSQL 9.x and PostGIS 1.5/2.0 several times and have never had this problem.
I just got a new CentOS 6.3 server up and running and and I have Postgres 9.3 functioning as expected. I have run
yum install postgis2_93
and I can see the files in
however, when I run
CREATE EXTENSION postgis;
ERROR: could not open extension control file "/usr/pgsql-9.3/share/extension/postgis.control": No such file or directory
What am I missing?
