+ <para>
+ The backend is in a transaction, but is currently not executing a specific query.
+ This state usually occurs when the application has initiated a transaction and
+ [possibly] executed some number of queries; without issuing a COMMIT / END / ROLLBACK,
+ the application is not in active use of a transaction, but the transaction is still
+ open.

+ NB: The <structname>waiting</> and <structname>state</> columns are independent. If a query is in the
+ <structname>active</> state, it may or may not be <structname>waiting</>. If a query is <structname>active</>
+ and <structname>waiting</> is true, it means that the query is being executed, but is being blocked by a lock
+ somewhere in the system. This is a distinctly different state than <structname>idle in transaction</> which
+ refers to the backend being idle after having initiated an explicit transaction
