FAQ for the PostgreSQL JDBC Driver Upgrade
What is happening?
We have upgraded the JDBC driver for the PostgreSQL Snap Pack from v9.4.1207 to v42.7.2 (Java 8). This upgrade will be part of the GA release on August 14, 2024 (Stable release). As a part of this upgrade, the 42.7.2 JDBC driver is bundled with the PostgreSQL Snap Pack as the default JDBC driver.
Why are we upgrading the PostgreSQL driver?
To improve security, performance, stability, and reliability.
What is the timeline for this upgrade?
This upgrade is now available with the Snap Pack version 437patches27172 for PostgreSQL. This driver upgrade will be part of the GA release on August 14, 2024 (Stable release).
Will I be impacted?
Yes, you will be impacted if you use the default version. The impact might be minimal if you use the latest driver or a higher version than the v42.7.2 (Java 8) JDBC driver.
...
You will not be impacted if you provide your own custom driver.
Do I need to reconfigure my accounts?
No, you do not have to reconfigure your account settings or drivers; the account can remain as-is to work with the latest driver. However, if you currently use the default version and want to revert to the previous version behavior, we recommend you use the postgres 9.4.1207.jar.
We recommend you investigate your pipelines and check the Snaps downstream of PostgreSQL snaps for any of the affected scenarios. Update any dependencies that the downstream Snaps might have with respect to the changing error and outputs (especially in expressions) to conform to the new expected errors and outputs. Learn more about the change in errors and outputs for the new (v42.7.2) JDBC driver.
How can I verify that the changes work?
In a production Org
If you have a production Org to validate connections to your PostgreSQL instances, you may upload a PostgreSQL JDBC driver JAR compatible with
postgres 9.4.1207.jar.Upload that JAR file to your Org’s shared folder and specify it in the PostgreSQL Account.
Validate the account.
After you verify that the updated JDBC driver works, you may remove it.
How do you override the behavior changes?
Use the postgres 9.4.1207.jar from v9.4.1207 to maintain the same behavior as before the driver upgrade.
Behavior Changes
Changes in the query in the error messages:
Some error messages will now include the data type for certain values, for example:
Old:
"...where (badId = 1) was aborted:..."New:
"...where (badId = ('1'::numeric)) was aborted:..."
Improvisations in error messages:
There are some minor text changes to few of the error messages, for example:
Old:
"Hint: No operator matches the given name and argument types."New:
"Hint: No operator matches the given name and argument type(s)."
