A connection-level property to customize query behavior. Under JDBC, these correspond directly to connection properties passed to the DriverManager. Under ODBC, these correspond to properties in the connection string.
Currently supported connection properties:
time_zone - Represents the default timezone used to run the query.
session_id - Associates the query with a given session.
Additional properties are allowed, but ignored. Specifying multiple connection properties with the same key returns an error.
