-- Firstly, remove PRIMARY KEY attribute of former PRIMARY KEY
ALTER TABLE <table_name> DROP CONSTRAINT <table_name>_pkey;

-- Then change column name of  your PRIMARY KEY and PRIMARY KEY candidates properly.
ALTER TABLE <table_name> RENAME COLUMN <primary_key_candidate> TO id;

// To compile: clang++ -arch x86_64 -arch arm64 -std=c++20 library_injector.cpp -lbsm -lEndpointSecurity -o library_injector,
// then codesign with com.apple.developer.endpoint-security.client and run the
// program as root.

#include <EndpointSecurity/EndpointSecurity.h>
#include <algorithm>
#include <array>
#include <bsm/libbsm.h>
#include <cstdint>

 * If you know how to create an NSString instance whose class is actually NSString please let me know.
 * Other possible concrete subclasses of NSString are: NSConstantString, __NSCFConstantString, NSPathStore2, NSSimpleCString and __NSLocalizedString.
