Documentation Issue
What was unclear or otherwise insufficient?
I cannot find information on which column type is used if there is no explicit type given in a @Column() decorator. Does a string result in varchar or text? If it's a varchar, with what length? Similar for other types.
Recommended Fix
Add a table explaining which column type is used for every possible TypeScript type (or what happens if no appropriate column type exists).
