NAME

6       CREATE_ACCESS_METHOD - define a new access method
7

SYNOPSIS

9       CREATE ACCESS METHOD name
10           TYPE access_method_type
11           HANDLER handler_function
12

DESCRIPTION

14       CREATE ACCESS METHOD creates a new access method.
15
16       The access method name must be unique within the database.
17
18       Only superusers can define new access methods.
19

PARAMETERS

21       name
22           The name of the access method to be created.
23
24       access_method_type
25           This clause specifies the type of access method to define. Only
26           INDEX is supported at present.
27
28       handler_function
29           handler_function is the name (possibly schema-qualified) of a
30           previously registered function that represents the access method.
31           The handler function must be declared to take a single argument of
32           type internal, and its return type depends on the type of access
33           method; for INDEX access methods, it must be index_am_handler. The
34           C-level API that the handler function must implement varies
35           depending on the type of access method. The index access method API
36           is described in Chapter 60.
