This should have been done in the initial commit that made unix_socket_directories a list as of c9b0cbe. This change allows to support correctly the case of ALTER SYSTEM, where it is possible to specify multiple paths as a list, like the following pattern where flattening is applied to each item: ALTER SYSTEM SET unix_socket_directories = '/path1', '/path2'; Any parameters specified in postgresql.conf are parsed the same way, so there is no compatibility change. pg_dump has a hardcoded list of parameters marked with GUC_LIST_QUOTE, that gets its routine update. These are reordered alphabetically for clarity.
