Code that prints out the contents of setconfig or proconfig arrays in SQL format needs to handle GUC_LIST_QUOTE variables differently from other ones, because for those variables, flatten_set_variable_args() already applied a layer of quoting. The value can therefore safely be printed as-is, and indeed must be, or flatten_set_variable_args() will muck it up completely on reload. For all other GUC variables, it's necessary and sufficient to quote the value as a SQL literal. We'd recognized the need for this long ago, but mis-analyzed the need slightly, thinking that all GUC_LIST_INPUT variables needed the special treatment. That's actually wrong, since a valid value of a LIST variable might include characters that need quoting, although no existing variables accept such values. More to the point, we hadn't made any particular effort to keep the various places that deal with this up-to-date with the set of variables that actually need special treatment, meaning that we'd do the wrong thing with, for example, temp_tablespaces values. This affects dumping of SET clauses attached to functions, as well as ALTER DATABASE/ROLE SET commands. In ruleutils.c we can fix it reasonably honestly by exporting a guc.c function that allows discovering the flags for a given GUC variable. But pg_dump doesn't have easy access to that, so continue the old method of having a hard-wired list of affected variable names. At least we can fix it to have just one list not two, and update the list to match current reality. A remaining problem with this is that it only works for built-in GUC variables. pg_dump's list obvious knows nothing of third-party extensions, and even the "ask guc.c" method isn't bulletproof since the relevant extension might not be loaded. There's no obvious solution to that, so for now, we'll just have to discourage extension authors from inventing custom GUCs that need GUC_LIST_QUOTE. This has been busted for a long time, so back-patch to all supported branches.
