Top interview questions to hire PostgreSQL developers.

Whether you're an IT recruiter or a project manager, you know that finding top developers is critical to the success of your project. Here are some sample interview questions to use when looking for a new PostgreSQL developer to work on your online applications.

Currently, the stable version of PostgreSQL is 13.4. It has several new features, such as improved performance, better query planning, parallelized vacuuming of indexes, among others. It is very important to keep yourself updated with the latest version of tools you are using.

PostgreSQL is an object-relational DBMS, while MySQL is a community-driven DBMS system. Also, PostgreSQL supports modern application features and MySQL only supports JSON.

PostgreSQL is object-relational, this makes the database more flexible and robust than the others. The answer to this question reflects the level of expertise the PostgreSQL developer has. Answering the advantages demonstrates that a developer is familiar with PostgreSQL’s core design and architecture.

Developers must start the database server before they can access the database. The database server program is called Postgres. To set up a PostgreSQL Media Server database on Windows, developers must download and install a PostgreSQL server, then they must add the PostgreSQL bin directory path to the PATH environment variable, and so on.

Multi-version concurrency control or MVCC allows PostgreSQL developers to avoid unnecessary locking of the database.

In PostgreSQL, the base directory is the folder where PostgreSQL stores all the data developers have stored in the databases.
