librespeed-rust exited with code 133 (restarting)

psql setup:

postgres=# CREATE USER librespeed WITH PASSWORD 'librespeedpass';
CREATE ROLE
postgres=# CREATE DATABASE speedtest OWNER librespeed;
CREATE DATABASE
postgres=# 
\q

config:

# database config for : mysql, postgres, sqlite, memory, or disable by write none
# after restarting the service, the in-memory database is reset
# if none is specified, no telemetry/stats will be recorded, and no result JPG will be generated
database_type="postgres"
database_hostname="192.168.10.23"
database_name="speedtest"
database_username="librespeed"
database_password="librespeedpass"
# if you use `sqlite` as database, set database_file to database file location
database_file="speedtest.db"

Start with src/database/postgres.rs at line 94 and reproduce the crash using the PostgreSQL setup and config shown in the issue. Inspect how the blocking database operation is run on the async runtime. Done means the service starts with PostgreSQL enabled and does not panic or restart with the reported runtime error.
