dbcli/pgcli: Postgres CLI with autocompletion and syntax highlighting

pgcli is a command-line interface for PostgreSQL that offers features like auto-completion and syntax highlighting. It supports installation via pip, apt-get (for Debian-based systems), and Homebrew (for macOS). It can also be used within Docker and IPython consoles. Configuration options are extensive and can be set through environment variables or configuration files. Pgcli is built on Python's Prompt Toolkit and supports many of the same environment variables as psql.
