usql is a universal command-line interface for PostgreSQL, MySQL, Oracle Database,
SQLite3, Microsoft SQL Server, and many other databases including NoSQL and
non-relational databases!

usql provides a simple way to work with SQL and NoSQL databases via a command-line
inspired by PostgreSQL's psql. usql supports most of the core psql features,
such as variables, backticks, backslash commands and has additional features that
psql does not, such as multiple database support, copying between databases, syntax
highlighting, and context-based completion.

Database administrators and developers that would prefer to work with a tool like
psql with non-PostgreSQL databases, will find usql intuitive, easy-to-use, and a
great replacement for the command-line clients/tools for other databases.
