drogon_ctl create model ./models -o ./models -f givs segmentation fauld

**Describe the bug**
When running drogon_ctl create model to generate model classes from an existing PostgreSQL database table, the command crashes with a segmentation fault.

### To Reproduce
**Steps to reproduce the behavior:**

1. Prepare a config.json file with PostgreSQL connection info, including "db_clients" configuration.
3. Ensure the target database and table (e.g., book) exist in PostgreSQL.
4. Run the command:

`drogon_ctl create model ./models -o ./models --table=book -f -c config.json`
The command crashes immediately with:

`Segmentation fault (core dumped)`

**Expected behavior**
The model class files for the specified table should be generated without crashing.

**Screenshots**
N/A

Desktop (please complete the following information):
OS: Ubuntu 24.04

Drogon version: 1.9.10

Compiler: GCC 14.2

**Additional context**

- Database: PostgreSQL 16.9
-
- config.json contains a valid "db_clients" entry with correct host, port, dbname, user, and password fields.
-
- The table book exists in the public schema.
-
- Tried both JSON and YAML config files with the same issue.
-
- The segfault prevents any further debug information output.
-
- The issue occurs even with minimal config and a single table.

Please let me know if you need the config file or logs to help reproduce.
