Hi @radu5121 , you needed that extension probably for Drupal?
Have you solved that already?
I would like to do that also.
I have tried:
sudo -u postgres psql -d databasename -c "create extension pg_trgm;"
- inside PSQL prompt
CREATE EXTENSION pg_trgm SCHEMA addons;
ERROR: could not open extension control file "/www/server/pgsql/share/extension/pg_trgm.control": No such file or directory
But nothing worked for me.
