A new module is available in my forge: PostgreSQL 18 with pgAdmin 4 as web interface. Each instance is its own database server, with its own random postgres password and its own pgAdmin behind a Traefik route.
Backup, restore and clone use the standard NS8 machinery. The backup holds a logical pg_dumpall rather than the binary data directory, so snapshots stay small and can be restored into a fresh instance.
Add the repository:

Code and issues: GitHub - stephdl/ns8-postgresql18: NethServer 8 module for PostgreSQL 18 with pgAdmin · GitHub
Released as 1.0.0. First pgAdmin login is admin@nethserver.org / Nethesis,1234 — change it right away.
Feedback welcome.
