PostGIS for PGlite

Hi HN,

PostGIS has been one of the most requested extensions for PGlite and we've recently ported it. For now, it doesn't contain some optional libraries like json-c and GDAL, but we see a path in adding those as well.

You can try it directly in our REPL https://pglite.dev/repl

We're very interested in seeing what people build with it.
