postgres=# CREATE EXTENSION IF NOT EXISTS pgjwt WITH SCHEMA ext_pgjwt;
ERROR:  extension "pgjwt" is not available
DETAIL:  Could not open extension control file "/opt/bitnami/postgresql/share/extension/pgjwt.control": No such file or directory.
HINT:  The extension must first be installed on the system where PostgreSQL is running.

Let's enable debug and go in as root to add extension

postgresql.values.yaml

tls:
  enabled: true
  autoGenerated: true
primary:
  containerSecurityContext:
    enabled: true
    # runAsUser: 1001
    runAsUser: 0
  service:
    type: LoadBalancer
    annotations:
      metallb.universe.tf/address-pool: pool1
diagnosticMode:
  enabled: true

helm upgrade --install postgresql bitnami/postgresql -f postgresql.values.yaml --set audit.pgAuditLog=all

# apt-get install postgresql-server-dev-all
# cd /root/
/root # git clone https://github.com/michelp/pgjwt.git
cd pgjwt
/root/pgjwt# make install

output
