Bug Description

create PostgreSQL connection with following options:

{
   dialectOptions: {
       statement_timeout: 10,
   }
}

then when run next code

await sequelize.query('select * from tableName', { type: QueryTypes.RAW });

"Query read timeout" appeared immidiatly.
But then after 30s - 1m next error appears and destroys my server:
