"
When an error is caught by an EXCEPTION clause, the local variables of the
PL/pgSQL function remain as they were when the error occurred, but all
changes to persistent database state within the block are rolled back
​"​

You have either found a bug (documentation or code) or your actual code is
doing something more complex than what you are showing here. If you
provide a self-contained test case that exhibits the behavior you are
observing it will be possible to determine which of those two possibilities
apply.
