### Synapse
#### Setup db
delete synapse db and recreate with correct locale 
```sh 
PRIMARY_POD=$(kubectl -n datastore get pods --selector='postgres-operator.crunchydata.com/cluster=postgres,postgres-operator.crunchydata.com/role=master' -o jsonpath='{.items[*].metadata.labels.statefulset\.kubernetes\.io/pod-name}') 
PGPASSWORD=$(kubectl -n datastore get secrets  "postgres-pguser-grant" -o go-template='{{.data.password | base64decode}}')

kubectl -n datastore exec -it "$PRIMARY_POD" -- psql -c 'DROP DATABASE synapse;'
kubectl -n datastore exec -it "$PRIMARY_POD" -- createdb --encoding=UTF8 --locale=C --template=template0 --owner=synapse synapse
```
backup/restore db
```sh
kubectl -n datastore exec -it $PRIMARY_POD --  pg_dump -Upostgres -Fc --exclude-table-data e2e_one_time_keys_json synapse > synapse.dump

kubectl port-forward $PRIMARY_POD 5432:5432
PGSSLMODE=disable  pg_restore -h localhost -U synapse -vv -d synapse < synapse.dump

```
