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)

45f063d469 Aggregate small number of text items in overviews
Instead of nulling text fields for non-singleton aggregated records
concatenate distinct text values when they're few (5 or less).

c595e45c11 Add _vovw_count columnt to tables for which overviews are created

tiler only, but that makes the column hard to access from the editor.

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.

CDB_CreateOverview had to be executed with the user role
corresponding to the owner of the table; now it can be executed
by the postgres user.
