Description
if 2 concurrent calls to MutexApi.acquireLock() happen with the same "key" value and there is no row in AUX_TABLE for that value yet (i.e. both are attempting to insert it) Postgres kills the txn which gets the Duplicate Key error and no more statements can be executed on this txn.
(This is different from the way most DBs behave).
Caused by: MetaException(message:Unable to lock 'CheckLock' due to: ERROR: current transaction is aborted, commands ignored until end of transaction block (SQLState=25P02, ErrorCode=0);
