Compreface-API rewrites my postgresql jdbc url

**Describe the bug**

I supplied a custom jdbc url to my already running postgresql host. However the host name includes `postgresql` which gets rewritten into `psql` for some reason.

The `compreface-api` container image from version `0.6.0` until the latest has this issue, `0.5.1` works as intended.

Is that normal? Is there some code that replaces every string `postgresql` in the configuration by `psql`?

**To Reproduce**

Steps to reproduce the behavior:
1. Include `postgresql` in the host part of the environment variable `POSTGRES_URL`.
2. Profit

**Expected behavior**

My url is supposed to be used as-is, not overwritten by something I cannot control

`compreface-admin` does not have this issue, regardless of the version.

Start by inspecting how the compreface-api container handles the POSTGRES_URL environment variable, then compare version 0.5.1 with 0.6.0 or later using a host containing `postgresql`. Compare this behavior with compreface-admin. Done means the supplied JDBC URL is used unchanged and the regression is verified.
