-- Database integration with vim-dadbod
-- Supports PostgreSQL, MySQL, SQLite, and more
-- All three plugins are lazy-loaded:
--   - vim-dadbod loads on :DB / :DBUI* commands
--   - dadbod-ui loads on its own UI commands
--   dadbod-completion loads on sql/mysql/plsql filetypes
--
-- Keymaps live in config/keymaps.lua under the <leader>D group.
