36 * Certain options can only be set at certain times. The rules are
37 * like this:
38 *
39 * INTERNAL options cannot be set by the user at all, but only through
40 * internal processes ("server_version" is an example). These are GUC
41 * variables only so they can be shown by SHOW, etc.
42 *
43 * POSTMASTER options can only be set when the postmaster starts,
44 * either from the configuration file or the command line.
45 *
46 * SIGHUP options can only be set at postmaster startup or by changing
47 * the configuration file and sending the HUP signal to the postmaster
48 * or a backend process. (Notice that the signal receipt will not be
49 * evaluated immediately. The postmaster and the backend check it at a
50 * certain point in their main loop. It's safer to wait than to read a
51 * file asynchronously.)
52 *
53 * BACKEND and SU_BACKEND options can only be set at postmaster startup,
54 * from the configuration file, or by client request in the connection
55 * startup packet (e.g., from libpq's PGOPTIONS variable). SU_BACKEND
56 * options can be set from the startup packet only when the user is a
57 * superuser. Furthermore, an already-started backend will ignore changes
58 * to such an option in the configuration file. The idea is that these
59 * options are fixed for a given backend once it's started, but they can
60 * vary across backends.
61 *
62 * SUSET options can be set at postmaster startup, with the SIGHUP
63 * mechanism, or from the startup packet or SQL if you're a superuser.
64 *
65 * USERSET options can be set by anyone any time.

79 * The following type records the source of the current setting. A
80 * new setting can only take effect if the previous setting had the
81 * same or lower level. (E.g, changing the config file doesn't
82 * override the postmaster command line.) Tracking the source allows us
83 * to process sources in any convenient order without affecting results.
84 * Sources <= PGC_S_OVERRIDE will set the default used by RESET, as well
85 * as the current value.
86 *
87 * PGC_S_INTERACTIVE isn't actually a source value, but is the
88 * dividing line between "interactive" and "non-interactive" sources for
89 * error reporting purposes.
90 *
91 * PGC_S_TEST is used when testing values to be used later. For example,
92 * ALTER DATABASE/ROLE tests proposed per-database or per-user defaults this
93 * way, and CREATE FUNCTION tests proposed function SET clauses this way.
94 * This is an interactive case, but it needs its own source value because
95 * some assign hooks need to make different validity checks in this case.
96 * In particular, references to nonexistent database objects generally
97 * shouldn't throw hard errors in this case, at most NOTICEs, since the
98 * objects might exist by the time the setting is used for real.
99 *
100 * When setting the value of a non-compile-time-constant PGC_INTERNAL option,
101 * source == PGC_S_DYNAMIC_DEFAULT should typically be used so that the value
102 * will show as "default" in pg_settings. If there is a specific reason not
103 * to want that, use source == PGC_S_OVERRIDE.
104 *
105 * NB: see GucSource_Names in guc.c if you change this.
