1b0f77aa96 Always retain single-valued aggregated texts 
This makes columns which have the same value in a group to be aggregated
maintain that value (rather than replacing it by the multiple-value
indicator *) whatever the group value is. (Previously this happend
only for small groups)

Instead of nulling text fields for non-singleton aggregated records

f96163265b Fix bug for tables without geom or with no potential overviews 
If the table doesn't have geometries but the createoverviews function is
called, the current geometry type checks won't work because "null" will
not give a boolean value in the type comparisons.

Also, if the createoverviews function is called over a simple table with
would not require overviews according to the strategies it is handled
correctly.
