Nicolae Vartolomei b0f2f23a38 Test materialized view pushing extra columns 
This test exists to prevent unintended changes to existing behaviour.

Although this behaviour might not be ideal it is can be exploited for 0-downtime changes to materialized views.

Step 1: Add new column to source table.
Step 2: Create new view reading source column.
Step 3: Swap views using `RENAME TABLE`.
Step 4: Add new column to destination table as well.
