   I remember chatting with another developer on this. Note that this seems to be problem specific to JDBC; after #16805 (the PR fixing #16564), most task errors can correctly be logged—but not JDBC. In fact, the JDBC error does not even go through the code path implemented in the PR; when using JDBCOperator, you get *no errors at all*, not the *Task failed with exception* message an exception would normally trigger (for example, the Postgres example above would emit this log). My current hypothesis is JDBC (or the operator/hook) is swallowing the exception somehow and the scheduler never actually received it, let alone logging.
