sql_sizing
   The table sql_sizing contains information about
   various size limits and maximum values in
   PostgreSQL.  This information is
   primarily intended for use in the context of the ODBC interface;
   users of other interfaces will probably find this information to be
   of little use.  For this reason, the individual sizing items are
   not described here; you will find them in the description of the
   ODBC interface.
