I'd be concerned that what is missing here is the bigger issue of Best Practice #0: Use Bound Variables.
The only way I've seen invalid literals show up in SQL queries is through the dynamic generation of SQL Statements vs. using bound variables.
Not using bound variables is your doorway to SQL injection exploits.
9. Do NOT arbitrarily assign an "id" column to a table as a primary key when other columns are perfectly suited as a unique primary key.
...
Good example: CREATE TABLE accounts ( accout_id bigint NOT NULL ,
I would not consider the general use of natural primary keys to be best practice.
Let's assume your account_id field is used as a foreign key in a dozen other tables.
1) What happens if someone mis-types the account-id?
To correct that, you also need to correct the FK field in the other dozen tables.
2) What happens when your company starts a new project (or buys a competitor) and all the new account numbers are alpha-numeric?
3) Your example shows the id as a bigint, but your rule is not limited to integers.
What if your table is country populations and the primary key is country name?
Now, you have quite large foreign keys (and a country changing its name is not unheard of).
(and let's not even get started on case-sensitivity or character encodings).
