I'm not a Zed developer, but I'm pretty sure LSP interfaces are pretty much standardized now, in large part to VS Code's efforts, so they're pretty consistent across most editors that support them.

That doesn't mean Zed will have all the other extensions that VS Code has... Recently added the new SQL Server extension(s) and it's been at least interesting, in a way slightly better than using SMMS. It's pretty much burrowing the UI from Azure Data Studio (or whatever it was called). Haven't tried similar for PG/SQLite etc yet.
