It is geared toward database core developers, operation systems developers, system architects, and all those who want to understand databases in more detail.
These skills are also applicable to any other major SQL database, such as MySQL, Microsoft SQL Server, Amazon Redshift, Oracle, and much more. GitHub is home to over million developers working together to host and review code, manage projects, and build software together. This may be possibly because the psql binary seems to be missing.
