No, it's not.   I'm afraid that your co-workers learned their computer
knowledge 10 years ago and have not kept up to date.  They may need
retraining.

Modern database systems, especially PostgreSQL, are much faster with a proper
relational schema than with an inadequate flat-file table, due to the
efficient storage of data ... i.e., no redundancy.

I highly suggest that you take a look at the book "Database Design for Mere
Mortals"; if you're asking the question you posted, you are nowhere near
ready to build a production database application.
