postgresql_extensions.control -> no such file or directory

[rgdts]

myapp: failed: [127.0.0.1] (item=postgresql_extensions) => {"changed": true, "cmd": "psql myapp -c 'CREATE EXTENSION IF NOT EXISTS postgresql_extensions;'", "delta": "0:00:00.053190", "end": "2017-09-08 17:56:30.268541", "failed": true, "item": "postgresql_extensions", "rc": 1, "start": "2017-09-08 17:56:30.215351", "stderr": "ERROR: could not open extension control file "/usr/share/postgresql/9.3/extension/postgresql_extensions.control": No such file or directory", "stderr_lines": ["ERROR: could not open extension control file "/usr/share/postgresql/9.3/extension/postgresql_extensions.control": No such file or directory"], "stdout": "", "stdout_lines": []}

Does anybody know what could be causing this?
