Hi, I constantly get 'waiting' status when I execute some ddl statement and some client connections is in idle transaction. For example, try to remove not null constraint and has client connection in "idle in transaction" status. This situation always get TABLE waiting. Another situation, is to drop a table and for sure doesn't have transactions involved, and always get status "DROP TABLE waiting" Is this normal? Other databases doesn't happen this.
