[postgis-users] mulitpolygon with type set to geometry(Geometry, 4326)

[Jason Mathis]

ah yes that works. Turns out you have to drop and create the view if I tried a replace i get the below message. 

    ERROR:  cannot change data type of view column "pt_geom" from geometry to geometry(Point,4326)

But a new view shows up correctly. 

Thanks!

Hello Jason,

All you need to cast a geometry as other more restrict geometry type is:

st_centroid(report_geom)::geometry(POINT,4326)

Hope this helps

Hello,

I am fairly new to postgis so it would be great if someone could point me in the right direction on how to fix this issue. Or if its even fixable. 

I have a table that stores polygons and multi polygons with a column:

    report_geom geometry(Geometry,4326)

I have a view that uses that column like:

    st_centroid(report_geom) as pt_geom

The issue is when you use the st_centroid is removes the srid and leaves it a plain geometry. Which can make it a bit inconvenient for use in arc and qgis apps. Is there a way to cast it to be a point with 4326? 

Thanks all!
