[Bug]: Activepieces PostgreSQL 18 volume mount path incorrect

[Elandlord]

Error Message and Logs

PostgreSQL data does not persist after container restart.

Volume mounts to /var/lib/postgresql/data but PostgreSQL 18 uses /var/lib/postgresql/18/docker.

Steps to Reproduce

1. Deploy Activepieces using one-click service template
2. Create a flow or any data in Activepieces
3. Restart using Coolify
4. Data is lost because PostgreSQL 18 writes to a different path than the mounted volum

Example Repository URL

No response

Coolify Version

v4.0.0-beta.462

Are you using Coolify Cloud?

No (self-hosted)

Operating System and Version (self-hosted)

Ubuntu 22.04.5

Additional Information

The template uses postgres:18-alpine but the volume still points to the old path /var/lib/postgresql/data.

PostgreSQL 18 uses /var/lib/postgresql/18/docker.

Additionally, the AP_SIGN_UP_ENABLED environment variable is missing from the template, which controls whether new user registration is allowed.

Yeah I just woke up to all my databases gone 😢 Happy backup restore day

Btw, cheers for the super handy integrated backup tool. This helped me restore all databases. Only issue, I couldn't do it through the UI. I needed to expose a port and do it from my machine by using pg_restore locally
