Compile supabase PostgreSQL with libxslt

[davidaventimiglia-professional]

It'd be cool if supabase PostgreSQL was (re)compiled with libxslt support. The xml2 extension is available, of course, but functions like xslt_process don't work without libxslt. Now, I get that xml2 is deprecated and I get that every additional library makes the compiled image bigger, so I don't expect this actually to happen. I'm not even sure I recommend it. But, it would be super cool to have a templating (really a transformation) engine right in the database. Something to consider.
