I recently started using pgModeler for working with my PostgreSQL database schemas. The software is opensource and free to use but must be compiled by the user. There is also an option to pay for the download of pre-compiled binaries. pgModeler is available for Windows, Linux and macOS.
There is functionality allowing you to export schema images and SQL files.
There is also the option to change relationship diagram styles.
Tables are easily created using the Table Properties dialog.
