The submitter doesn't seem to be in any way connected to the project, so this seems to just organically be interesting and still new for enough people––I hadn't seen the earlier posts, for example, and I check HN quite obsessively.

Also: "assume good faith..."

I wouldn't call it spam, but it does seem odd for a really immature product to keep hitting the front page.

I think it indicates demand for a good open source SQL editor. (I myself am reasonably happy with DBeaver which also has a paid version I believe)

When this happens you can just comment with a link to the older submissions (which others have done) and email the mods.
