Hello everyone, we hope you are doing great !
You can't use ArcGIS Server without a license.
You can't enable an enterprise geodatabase in PostgreSQL without a Server license.
You can't use MySQL as an enterprise geodatabase (even with a license)
You can use PostgreSQL/PostGIS with Desktop (ArcMap/Pro) without a Server license, but you can't do editing or UpdateCursor or any geodatabase functionality (you can upload new tables, insert to existing tables, and query tables, plus issue SQL in ArcPy, but that's about it).
All the documentation is online and in the software install.
Portal is the Enterprise component that correlates to AGOL, though there are compatibility issues, since AGOL sees updates/new functionality before it is ported to Portal.

Thanks for your response.
Can we get an ArcGIS Server with our ArcGIS Advanced License, or do we need an enterprise license ?
ArcGIS Server is part of Enterprise.
