Oops, and I'm only just trying to catch up! Thanks once again @tt4g for jumping in. @Broollie I did notice this one little thing: ```cxx static Data from_string(std::string_view text) {...

(I took the liberty to edit the code snippets you posted above: when you add "cxx" after the three backticks at the beginning, you get C++ syntax highlighting. :-)

And I must admit that the mechanism by which libpq figures out the types of the parameters is mysterious to me as well. By the way if you're working in...

The `configure` or `cmake` step to the libpqxx build should detect whether your compiler supports concepts. I'm writing this on my phone where it's hard to look up past conversation......

@Broollie when building libpqxx, did you use `configure` or `cmake`? If you used `configure` then the file `config.log` should show whether the configure script found `__cpp_concepts` defined or not. (And...

Ah yes, the forbidden conversion - I guess that's two concepts clashing. A span of contiguous `std::byte` should act as a `bytea`. And I was expecting a `std::array` of `std::byte`...

Or, given that the most specific specialisation should normally win out, perhaps it's a matter of removing a `string_traits` specialisation that has now become too specific.

@Broollie for now I'm just utterly stuck on getting readthedocs working again. I'm rebuilding that from scratch, because I see no other way at this point. Hopefully after that I...

The good news is that I got the documentation build working again. (With lots of scary warning messages, so I'll be chipping away at that pile still.) I've got one...

Reading this back again, I think what I need to do about this ticket is write a test that does conversions of a `std::array`... and then make that test work....
