NAME

       DROP_PROCEDURE - remove a procedure

SYNOPSIS

       DROP PROCEDURE [ IF EXISTS ] name [ ( [ [ argmode ] [ argname ] argtype [, ...] ] ) ] [, ...]
           [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP PROCEDURE removes the definition of an existing procedure. To execute this command
       the user must be the owner of the procedure. The argument types to the procedure must be
       specified, since several different procedures can exist with the same name and different
       argument lists.

PARAMETERS

       IF EXISTS
           Do not throw an error if the procedure does not exist. A notice is issued in this
           case.

       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 DROP 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.

       CASCADE
           Automatically drop objects that depend on the procedure, and in turn all objects that
           depend on those objects (see Section 5.14).

       RESTRICT
           Refuse to drop the procedure if any objects depend on it. This is the default.

EXAMPLES

           DROP PROCEDURE do_db_maintenance();

COMPATIBILITY

       This command conforms to the SQL standard, with these PostgreSQL extensions:

       •   The standard only allows one procedure to be dropped per command.

       •   The IF EXISTS option

       •   The ability to specify argument modes and names
