## 52.77. `pg_prepared_statements`

[]()

 The `pg_prepared_statements` view displays all the prepared statements that are available in the current session. See [PREPARE](sql-prepare.html) for more information about prepared statements.

`pg_prepared_statements` contains one row for each prepared statement. Rows are added to the view when a new prepared statement is created and removed when a prepared statement is released (for example, via the [`DEALLOCATE`](sql-deallocate.html) command).
