module named 'psycopg2' during k8 installation
OK - I had an extra line break '\' at the end of the pip install. Removed that
and I have
```
bootstrapScript: |
#!/bin/bash
# Install system-level dependencies
apt-get update && apt-get install -y
uv pip install \
authlib \
psycopg2-binary \
mysqlclient
# Create bootstrap file if it doesn't exist
if [ ! -f ~/bootstrap ]; then
echo "Running Superset with uid {{ .Values.runAsUser }}" > ~/bootstrap
fi
```
Still errors:
```

ModuleNotFoundError: No module named 'psycopg2'
```
So its failing to build mysqlclient, which I guess is a requirement for
psycopg2. But unclear how to specify `MYSQLCLIENT_CFLAGS and
MYSQLCLIENT_LDFLAGS` or `valid pkg-config`....
