- Provides PostgreSQL server as shared database infrastructure - Follows KISS principle with only essential configuration (11 variables vs 45 originally) - Implements maximum security with Unix socket-only superuser access - Uses scram-sha-256 authentication for application users - Includes SystemD security hardening - Applications manage their own databases/users via this infrastructure - Production-ready with data checksums and localhost-only access

# Infrastructure Notes
|
|
# =================================================================
|
|
# This role provides minimal PostgreSQL infrastructure
|
|
# Applications should create their own databases/users:
|
|
#
|
|
# - postgresql_user:
|
|
# name: myapp
|
|
# password: "{{ vault_myapp_password }}"
|
|
# - postgresql_db:
|
|
# name: myapp
|
|
# owner: myapp
|
|
#
|
|
# PostgreSQL's built-in defaults are used for everything else |
