[postgis-users] identifying blank geometry fields

[Bob Hume]

Well, apparently it is a problem of pgAdmin not displaying the the_geom 
data, not that it doesn't exist.  Query  --   select name, the_geom, 
St_Length(the_geom) from dum;    --   shows a length for each row that 
appears to have a blank the_geom field.  I guess that explains why 
trying to find the blank the_geom fields with null didn't work; they 
aren't null.  I tried running the query in psql, but have a windows 
console conflict and don't want to take the time to figure out how to 
fix it so I can run the query directly in psql in Windows.  I'm a rookie 
and pgAdmin is enough for me.

Thanks all for the prompt and good troubleshooting suggestions.
