Usage

omni_types: Advanced types

The omni_types extension provides advanced type utilities, including function signature types that capture complete function signatures and allow direct invocation.

Define a Function Signature Type

Explicit definition:

SELECT omni_types.function_signature_type('sig', 'text', 'int');
-- Creates type 'sig' for functions accepting text and returning int

From existing function:

SELECT omni_types.function_signature_type_of('sig', 'length(text)');

Cast Functions to the Type 

SELECT 'length'::sig;

For non-failing validation:

SELECT sig_conforming_function('length');  -- returns NULL if no match

Invoke Typed Functions 

SELECT call_sig('length', 'hello');  -- returns 5

The call_<TYPE> function is auto-generated for each signature type and executes the referenced function with the provided arguments.
