Hi,
Sorry to bother.=20
I have encountered the following problem, please help me.
The attached file is a backup file of two geometries, the table name is
<temp_union_test>, the column of geometry is <the_geom>.
when I execute < select distinct the_geom from temp_union_test >, there =
is
only one row returned, but actually, the two geometries is totally
different.
I have tried this execution on PostgreSql 9.0 and PostgreSql 9.5, the
results is always the same.
Would you help me to solve this problem?
If you have any concern about it, I would be very appreciate it.
Thank you.
