This is a PostgreSQL list - you'd probably be better using a 
Microsoft-Access list.

In general terms, with MS-Access, I'd build separate queries for each 
step. So you'd want a query for:
1. Reset table3
2. Insert to table3 rows in table1 and not in table2
3. Insert to table3 rows in table2 and not in table1
...etc...
