Use native PostgreSQL result as expected result in AbstractWireProtocolTypeTest

[AShiou]

In AbstractWireProtocolTypeTest, we aim to test that the Wire Protocol type result is the same as the PostgreSQL type result. Therefore, there is no need to manually write the expected result. Instead, we should assert whether the Wire Protocol type result matches the PostgreSQL type result.

Possible Solution

To achieve this, we can modify the execute function in AbstractWireProtocolTypeTest to execute the same SQL query separately using PostgreSQL and the Wire Protocol, and then compare the query results.
