| Column | Type | Description / reference |
|---|---|---|
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.

prepare_time | timestamptz | The time at which the prepared statement was created |
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. |
result_types | regtype[] | The types of the columns returned by 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. If the prepared statement does not provide a result (e.g., a DML statement), then this field will be null. |
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 |
