One binary, no Electron. The editor is checked by PostgreSQL itself, the object browser is a DDL dump you can execute again, and the workspace comes back as you left it.
Per OS installs, the first connection the psql way, discovery from the project you opened, the workspace that restores.
Completion from the statement's scope, PostgreSQL linting as you type, function bodies checked without creating them, psql's commands in the editor.
The DDL snapshot on disk with statistics on every row, and a results grid you can filter, edit in place and export.
Query, command and grid extensions as plain files, with a published annotation format and 48 starters.
Read only enforced by PostgreSQL, a production guard on two axes, a commit gate, passwords that never leave the machine.
The annotation specification, the grid extension format, result views, the console line, supported PostgreSQL versions.
