         * THROTTLE:
         *
         * There was considerable discussion in late July, 2000 regarding
         * slowing down pg_dump when backing up large tables. Users with both
         * slow & fast (multi-processor) machines experienced performance
         * degradation when doing a backup.
         *
         * Initial attempts based on sleeping for a number of ms for each ms
         * of work were deemed too complex, then a simple 'sleep in each loop'
         * implementation was suggested. The latter failed because the loop
         * was too tight. Finally, the following was implemented:
         *
         * If throttle is non-zero, then
         *      See how long since the last sleep.
         *      Work out how long to sleep (based on ratio).
         *      If sleep is more than 100ms, then
         *          sleep
         *          reset timer
         *      EndIf
         * EndIf
         *
         * where the throttle value was the number of ms to sleep per ms of
         * work. The calculation was done in each loop.
         *
         * Most of the hard work is done in the backend, and this solution
         * still did not work particularly well: on slow machines, the ratio
         * was 50:1, and on medium paced machines, 1:1, and on fast
         * multi-processor machines, it had little or no effect, for reasons
         * that were unclear.
         *
         * Further discussion ensued, and the proposal was dropped.
         *
         * For those people who want this feature, it can be implemented using
         * gettimeofday in each loop, calculating the time since last sleep,
         * multiplying that by the sleep ratio, then if the result is more
         * than a preset 'minimum sleep time' (say 100ms), call the 'select'
         * function to sleep for a subsecond period ie.
         *
         * select(0, NULL, NULL, NULL, &tvi);
         *
         * This will return after the interval specified in the structure tvi.
         * Finally, call gettimeofday again to save the 'last sleep time'.

     * store an empty string as the name when a constraint is marked as
     * attnotnull (this cues dumpTableSchema to print the NOT NULL clause
     * without a name); also, such cases are never NO INHERIT.
     *
     * We track in notnull_inh whether the constraint was defined directly in
     * this table or via an ancestor, for binary upgrade.
     *
     * Lastly, we need to know if the PK for the table involves each column;
     * for columns that are there we need a NOT NULL marking even if there's
     * no explicit constraint, to avoid the table having to be scanned for
     * NULLs after the data is loaded when the PK is created, later in the

     * the PK is created.

     * Another complication arises from columns that have attnotnull set, but
     * for which no corresponding not-null nor PK constraint exists.  This can
     * happen if, for example, a primary key is dropped indirectly -- say,
     * because one of its columns is dropped.  This is an irregular condition,
