NAME
ALTER_PROCEDURE - change the definition of a procedure
SYNOPSIS
ALTER PROCEDURE name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ]
action [ ... ] [ RESTRICT ]
ALTER PROCEDURE name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ]
RENAME TO new_name
ALTER PROCEDURE name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ]
OWNER TO { new_owner | CURRENT_USER | SESSION_USER }
ALTER PROCEDURE name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ]
SET SCHEMA new_schema
ALTER PROCEDURE name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ]
DEPENDS ON EXTENSION extension_name
where action is one of:
[ EXTERNAL ] SECURITY INVOKER | [ EXTERNAL ] SECURITY DEFINER
SET configuration_parameter { TO | = } { value | DEFAULT }
SET configuration_parameter FROM CURRENT
RESET configuration_parameter
RESET ALL
DESCRIPTION
ALTER PROCEDURE changes the definition of a procedure.
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 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 needed to determine the
procedure's identity.
argtype
The data type(s) of the procedure's arguments (optionally schema-qualified), if any.
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
The name of the extension that the procedure is to depend on.
[ 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)) 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) and Chapter 19 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.
