CREATE EXTENSION pg_get_functiondef;

Usage

pg_get_functiondef: Get function’s definition

The pg_get_functiondef extension provides functions to retrieve the complete definition (DDL) of PostgreSQL functions and procedures, particularly useful in Oracle compatibility contexts within IvorySQL.

Enabling

CREATE EXTENSION pg_get_functiondef;

Retrieving Function Definitions

-- Get the DDL of a function by OID
SELECT pg_get_functiondef(oid) FROM pg_proc WHERE proname = 'my_function';

-- Get function definition by name
SELECT pg_get_functiondef('my_function'::regproc);

This extension extends the built-in pg_get_functiondef() to support Oracle-compatible function and procedure syntax used by IvorySQL, including PL/iSQL procedure bodies and Oracle-style parameter declarations.
