[postgis-users] Update "spatial_ref_sys" with "+towgs84" parameters

[Shane Spencer]

you could create a new entry, new srid, then update the geometry columns
table. I'm unsure on if you have to translate your data table to another
data table to update the srid per row/field.

I personally wouldn't modify any row of the spatial_ref_sys for
compatibility reasons.

Can you translate the coordinates after you query them and avoid updating
anything?
