This PR adds a new
st_read_meta
table function to read the metadata present in files readable by st_read.The output is similar to what you would get with
ogrinfo -json
but some fields are still missing. (like e.g.metadata
ironically). Still, this finally allows you to inspect the projection info of a GDAL dataset layer from within DuckDB.Closes #156
Also implements a small fix in the gdal virtual filesystem layer so that a failed stat call doesn't throw but instead returns -1.
