encrypted depends upon the underlying psql library and the
capabilities of the database server.
+The BSIZE subcommand serves only to optimise the speed of data transfer.
+It specifies an upper limit on
+number of cases to fetch from the database at once.
+The default value is 4096.
+If your SQL statement fetches a large number of cases but only a small number of
+variables, then the data transfer may be faster if you increase this value.
+Conversely, if the number of variables is large, or if the machine on which
+PSPP is running has only a
+small amount of memory, then a smaller value will be better.
