| * |
| * INTERNAL options cannot be set by the user at all, but only through |
| * internal processes ("server_version" is an example). These are GUC |
| * variables only so they can be shown by SHOW, etc. |
| * |
| * POSTMASTER options can only be set when the postmaster starts, |
| * either from the configuration file or the command line. |
| * |
| * SIGHUP options can only be set at postmaster startup or by changing |
| * the configuration file and sending the HUP signal to the postmaster |
| * or a backend process. (Notice that the signal receipt will not be |
| * evaluated immediately. The postmaster and the backend check it at a |
| * certain point in their main loop. It's safer to wait than to read a |
| * file asynchronously.) |
| * |
| * BACKEND options can only be set at postmaster startup, from the |
| * configuration file, or by client request in the connection startup |
| * packet (e.g., from libpq's PGOPTIONS variable). Furthermore, an |
| * already-started backend will ignore changes to such an option in the |
| * configuration file. The idea is that these options are fixed for a |
| * given backend once it's started, but they can vary across backends. |
| * |
| * SUSET options can be set at postmaster startup, with the SIGHUP |
| * mechanism, or from SQL if you're a superuser. |
| * |
| * USERSET options can be set by anyone any time. |
