The pg_cursors view lists the cursors that are currently available. Cursors can be defined in several ways:

The pg_cursors view displays cursors created by any of these means. Cursors only exist for the duration of the transaction that defines them, unless they have been declared WITH HOLD . Therefore non-holdable cursors are only present in the view until the end of their creating transaction.

Note: Cursors are used internally to implement some of the components of PostgreSQL , such as procedural languages. Therefore, the pg_cursors view might include cursors that have not been explicitly created by the user.
