Even with documentation, it is a lot to consume - someone on the project for a longer time can get more done definitely, but bringing on more people will lead to wildly different quality control. I find it do be a scaling problem if anything.

Would not splitting responsibility for the Database to more senior developers work better.

Not sure what you mean by quality control you don't enforce any coding standards / style guides for writing SQL.

It does sound like your employer is cheeping out and not hiring enough experienced developers

Management is an issue unfortunately, we need a larger developer team, he wants more sales. Yeesh.
