Fix 'ALTER MATERIALIZED VIEW ... REBALANCE' command
Problem description:
Attempts to rebalance a materialized view via
'ALTER MATERIALIZED VIEW ... REBALANCE' command (or via equivalently working for
materialized views 'ALTER TABLE ... REBALANCE') ended with an error:
'ERROR: cannot change materialized view ...'
Root cause:
The table rebalance logic tried to insert the data directly into the
materialized view as if it were an ordinary table. It is prohibited for
materialized views.
Fix:
Skip the call of 'ATExecShrinkTable()' for the materialized views. So during
'ALTER ... REBALANCE' only the distribution policy for the materialized view is
updated. And the user needs to perform 'REFRESH MATERIALIZED VIEW ...' after
the rebalance.
