Postage

Postage is a free PostgreSQL administration tool and a rich alternative to PGAdmin and PSQL. The application works as a modern, fast, event-based C-binary, built in the style of NGINX and Node.js.

Postage can autocomplete database objects and some keywords built in. The included ACE code editor has syntax highlighting, option-drag for selecting text vertically so you can set many options yourself. Postage can show object dependencies and dependents in graph format.
