Ticket #347 (closed defect: fixed)
Creating geography type is confusing
|Reported by:||robe||Owned by:||pramsey|
I'm not quite sure how to express this and not sure if I consider it an issue or not, but someone brought it to my attention when I was demonstrating how to create a column.
If you create a geography column as
geography(POINT,4326) vs. geography(POINT)
They are different. They don't have the same SRID and in order to convert a geography(POINT) to a geography(POINT,4326) you have to do something goofy like this
ALTER TABLE sometable ALTER COLUMN the_geog TYPE (geography(POINT,4326)) USING geography(ST_SetSRID(geometry(the_geog),4326) );
Given that we don't support unknown SRID -- it seems kind of silly to have people do this and takes a long time for a large table. Unfortunately not sure if there is anyway around this aside from enforcing the requirement of SRID (don't allow unknown for now, but allow it later when/if we support multiple SRIDs). I'm not sure what the best resolution is for this since its technically not a bug, but an annoyance.
