This may be virtual (created by GDAL for the SQL interface) and may be 0- or
1- based. Some drivers have actual names, and they are persistent and
arbitrary. Please use with caution, this function can return the current
FIDs, but there's no guarantee of what it represents for subsequent access.
An earlier version use 'OGRSQL' to obtain these names, which was slow for some
drivers and also clashed with independent use of the sql
argument.
vapour_read_names()
is an older name, aliased to vapour_read_fids()
.
