What's a proper data type to save coordinates in QGIS when using the 'Move label' tool?
real
double
numeric()
...
EDIT:
The CRS of the project is MGI / Austria GK East (31256).

Decimal (Real), just wit enough decimals to store the resulting coordinates. If you try to move points in a geographic coordinate system like 4326 it will need at least 6 decimals after the point. For projected CRS, that is up to you
When it comes to coordinates, always use double type if your data store allows you to. The reason is simple - it is always better to have higher positional precision (which you can round down if needed).
