* feat: add PostgreSQL with PgDog template
Add postgres-pgdog template providing PostgreSQL database with PgDog connection pooler, load balancer, and horizontal scaling proxy. Modern alternative to PgBouncer with multi-threading support.
- Configurable PostgreSQL (default: 18-alpine) and PgDog (default: v0.1.26) images
- Optional admin interface on port 6433
- Includes healthcheck and dependency management
* 🐛 fix(postgres-pgdog): add config mounts and fix postgres volume path
- Add [[config.mounts]] for pgdog.toml and users.toml
- Mount config files from ../files/ in docker-compose
- Change postgres volume to /var/lib/postgresql (postgres 18+ standard)
- Add explicit command with config paths to prevent warnings
* 🐛 fix(postgres-pgdog): correct binary path and use default config locations
- Mount configs to /pgdog/ (default WorkingDir) instead of /etc/pgdog/
- Remove explicit command (binary is /usr/local/bin/pgdog, not /pgdog/pgdog)
- Use image's default CMD with default config paths
* 🐛 fix(postgres-pgdog): remove invalid admin_port config field
- Remove admin_port from [general] section (not a valid field)
- Admin DB uses same port 6432 with special database name
- Remove commented admin domain config
* 🐛 fix(postgres-pgdog): enable external access via fixed port mapping
- Add fixed port 6432:6432 to postgres-pgdog service
- Remove HTTP domain config (incompatible with TCP protocol)
- Add comment for internal-only option
Fixes UnsupportedStartup errors when using domain config for PostgreSQL protocol access.
* 🐛 fix(postgres-pgdog): use standard port format per convention
- Change port mapping from '6432:6432' to '6432' format
- Follows Dokploy template convention for port declarations
- External access requires checking Dokploy UI for assigned host port
* 📝 docs(postgres-pgdog): clarify port settings comment
* 🐛 fix(postgres-pgdog): default to internal access with opt-in external port
- Remove obsolete version field
- Port mapping commented by default for security
- Users uncomment to enable external access on port 6432
