This includes the filename, FORMAT_LABEL, and the "$postgre$" prefix string. However, there's a more general issue: can't the same be implemented as a dynamic format? In fact, doesn't one of the predefined dynamic formats support these same hashes already? Maybe we should just document what predefined dynamic format should be used, and make this prominent in its FORMAT_NAME (so that it'll be seen on --test runs)? This general issue probably applies to several other formats as well, including e.g. "mongodb". And we know for sure it applies to "radmin" - we have both this format and the corresponding dynamic, clearly documented as such. Dynamic is faster per-core: it uses SIMD, whereas Dhiru's formats don't. However, it currently does not use OpenMP, whereas Dhiru's formats do. Is this reason enough to keep both for now, as separate formats? Even if so, shouldn't we have the separate formats that essentially duplicate dynamics use the corresponding $dynamic_*$ prefixes instead of their own ones? This brings up the issue of which of the two formats should be the default, though - but maybe that's a better issue to have than not even informing the user of the possibility to use a dynamic for the same thing (and better per-core speed), like what we have now.
