It's partly that, and mostly to ensure that the variable has some valid value even before the configuration file has been read. The latter consideration might or might not be important for BgWriterDelay in particular; but it is important for some GUC variables, so we tend to follow the coding pattern of initializing GUC variables to their defaults whenever practical. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
