orm: segfault when having nested foreign keys

[mak3e]

Describe the bug

If I define a foreign key relation to a table that has foreign key relation of its own the code compiles but results a runtime segfault even without a database connection.

Expected Behavior

No segfault

Current Behavior

signal 11: segmentation fault

Reproduction Steps

module main

import db.pg

[table: 'example']
pub struct Example {
    id        int        [primary; sql: serial]
    example2s []Example2 [fkey: 'example_id']
}

[table: 'example2']
pub struct Example2 {
    id         int        [primary; sql: serial]
    example_id int
    example3s  []Example3 [fkey: 'example2_id']
}

[table: 'example3']
pub struct Example3 {
    id          int [primary; sql: serial]
    example2_id int
}

fn main() {
    db := pg.connect(pg.Config{}) or { exit(0) }
    sql db {
        create table Example3
        create table Example2
        create table Example
    } or { print(err) }
}

Got the same issue and I wonder if there is a fix planned already?
