You must own the procedure to use **ALTER** **PROCEDURE**. To change a procedure's schema, you must also have CREATE privilege on the new schema. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have CREATE privilege on the procedure's schema. (These restrictions enforce that altering the owner doesn't do anything you couldn't do by dropping and recreating the procedure. However, a superuser can alter ownership of any procedure anyway.) ## PARAMETERS _name_ The name (optionally schema-qualified) of an existing procedure. If no argument list is specified, the name must be unique in its schema. _argmode_ The mode of an argument: IN, OUT, INOUT, or VARIADIC. If omitted, the default is IN. _argname_ The name of an argument. Note that **ALTER** **PROCEDURE** does not actually pay any attention to argument names, since only the argument data types are used to determine the procedure's identity. _argtype_ The data type(s) of the procedure's arguments (optionally schema-qualified), if any. See DROP PROCEDURE (**DROP**___**[PROCEDURE**(7)](https://www.chedong.com/phpMan.php/man/PROCEDURE/7/markdown)) for the details of how the procedure is looked up using the argument data type(s). _new_name_ The new name of the procedure. _new_owner_ The new owner of the procedure. Note that if the procedure is marked SECURITY DEFINER, it will subsequently execute as the new owner. _new_schema_ The new schema for the procedure. _extension_name_ This form marks the procedure as dependent on the extension, or no longer dependent on the extension if NO is specified. A procedure that's marked as dependent on an extension is dropped when the extension is dropped, even if cascade is not specified. A procedure can depend upon multiple extensions, and will be dropped when any one of those extensions is dropped. [ EXTERNAL ] SECURITY INVOKER [ EXTERNAL ] SECURITY DEFINER Change whether the procedure is a security definer or not. The key word EXTERNAL is ignored for SQL conformance. See CREATE PROCEDURE (**CREATE**___**[PROCEDURE**(7)](https://www.chedong.com/phpMan.php/man/PROCEDURE/7/markdown)) for more information about this capability. _configuration_parameter_ _value_ Add or change the assignment to be made to a configuration parameter when the procedure is called. If _value_ is DEFAULT or, equivalently, RESET is used, the procedure-local setting is removed, so that the procedure executes with the value present in its environment. Use RESET ALL to clear all procedure-local settings. SET FROM CURRENT saves the value of the parameter that is current when **ALTER** **PROCEDURE** is executed as the value to be applied when the procedure is entered. See [**SET**(7)](https://www.chedong.com/phpMan.php/man/SET/7/markdown) and Chapter 20 for more information about allowed parameter names and values. RESTRICT Ignored for conformance with the SQL standard. ## EXAMPLES To rename the procedure insert_data with two arguments of type integer to insert_record: ALTER PROCEDURE insert_data(integer, integer) RENAME TO insert_record; To change the owner of the procedure insert_data with two arguments of type integer to joe: ALTER PROCEDURE insert_data(integer, integer) OWNER TO joe; To change the schema of the procedure insert_data with two arguments of type integer to accounting: ALTER PROCEDURE insert_data(integer, integer) SET SCHEMA accounting; To mark the procedure insert_data(integer, integer) as being dependent on the extension myext: ALTER PROCEDURE insert_data(integer, integer) DEPENDS ON EXTENSION myext; To adjust the search path that is automatically set for a procedure: ALTER PROCEDURE check_password(text) SET search_path = admin, pg_temp; To disable automatic setting of _search_path_ for a procedure: ALTER PROCEDURE check_password(text) RESET search_path; The procedure will now execute with whatever search path is used by its caller. ## COMPATIBILITY This statement is partially compatible with the **ALTER** **PROCEDURE** statement in the SQL standard. The standard allows more properties of a procedure to be modified, but does not provide the ability to rename a procedure, make a procedure a security definer, attach configuration parameter values to a procedure, or change the owner, schema, or volatility of a procedure. The standard also requires the RESTRICT key word, which is optional in PostgreSQL. ## SEE ALSO CREATE PROCEDURE (**CREATE**___**[PROCEDURE**(7)](https://www.chedong.com/phpMan.php/man/PROCEDURE/7/markdown)), DROP PROCEDURE (**DROP**___**[PROCEDURE**(7)](https://www.chedong.com/phpMan.php/man/PROCEDURE/7/markdown)), ALTER FUNCTION (**ALTER**___**[FUNCTION**(7)](https://www.chedong.com/phpMan.php/man/FUNCTION/7/markdown)), ALTER ROUTINE (**ALTER**___**[ROUTINE**(7)](https://www.chedong.com/phpMan.php/man/ROUTINE/7/markdown)) PostgreSQL 14.23 2026 ALTER [PROCEDURE(7)](https://www.chedong.com/phpMan.php/man/PROCEDURE/7/markdown)
