Problem

postgres_dba works correctly inside psql. When run inside rpg in interactive mode (e.g. via tmux command injection), the :dba menu can be entered but cannot be exited — the user is stuck.

Steps to reproduce

1. Connect to Postgres with rpg in interactive mode
2. Trigger the postgres_dba menu (e.g. send \i path/to/postgres_dba/start.psql or :dba)
3. Try to exit the menu

Expected

Behaves identically to psql — menu navigation and exit work correctly.

Actual

Exit does not work; user cannot leave the postgres_dba menu.

Notes

• postgres_dba uses psql meta-commands and \prompt for interactive menus
• Likely a gap in rpg's \prompt or interactive input handling
• Blocking for users who rely on postgres_dba as part of their workflow
• Should be fixed as part of the v0.9.0 psql compatibility push
