Postgresql: Can't access to file « $libdir/postgis-2.1 » no such file or directory

Question

I guess this is a known issue but since I have used a script that removed my postgresql-9.4-postgis-2.1, I\'m now unable to get rid of this SQL error under Debian.

Answer 1

If you are using ubuntu

Enter in postgres interactive shell by using below command

• sudo -u postgres psql

• \c database_name;

• ALTER EXTENSION postgis UPDATE TO "2.4.4";

• SELECT PostGIS_Full_Version();
