<para>PgAdmin doesn't show anything for large geometries. The best ways to verify you do have day in your geometry columns are?</para>
|
||||
|

|
||||
<programlisting>-- this should return no records if all your geom fields are filled in
|
||||
SELECT somefield FROM mytable WHERE geom IS NULL;</programlisting>
|
||||
|
||||
<programlisting>-- To tell just how large your geometry is do a query of the form
|
||||
--which will tell you the most number of points you have in any of your geometry columns
|
||||
SELECT MAX(ST_NPoints(geom)) FROM sometable;</programlisting>
