## 56.15. `pg_prepared_statements`

The `pg_prepared_statements` view displays all the prepared statements that are available in the current session. See PREPARE 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` command).

Column Type Description
`name` `text` The identifier of the prepared statement
`statement` `text` The query string submitted by the client to create this prepared statement. For prepared statements created via SQL, this is the `PREPARE` statement submitted by the client.

`parameter_types` `regtype[]` The expected parameter types for the prepared statement in the form of an array of `regtype`. The OID corresponding to an element of this array can be obtained by casting the `regtype` value to `oid`.
`from_sql` `bool` `true` if the prepared statement was created via the `PREPARE` SQL command; `false` if the statement was prepared via the frontend/backend protocol
