[Qgis-user] Options when loading layers into PostGIS with DBManager

[Michael Dufty]

Hi,
I am trying out saving data in PostGIS, and have got stuck on the upload “import layer/file” dialog in DB Manager.

Can anyone recommend a good reference on what options should be selected?
It seems to fall into a gap between PostGIS documentation and QGIS documentation and I can’t find any information on what should be selected in what circumstances.

In particular
Primary key – should this be ticked and the existing id field selected? What happens if it is left unticked?
Geometry column – is this needed? Objects still seem to have geometry if it is left out.
Create spatial index – this sounds like a good idea, but the one youtube tutorial I found (Klas Karlson) he left it unticked and said the layer already had everything.  Is it needed for some source formats and not others eg shapefile vs geopackage?

Convert field names to lower case doesn’t sound very useful, but I presume it is there for a reason, does anyone know the circumstances that would be needed?

Cheers,
