<p>Hello,</p>
<p>we want to use QGIS to document our cable Infrastructure (We are
an ISP). Now the Problem is, that 3 or 4 persons have to work with
QGIS. Now my Idea was to provide a Postgresql Server with postgis
installed. Thats working fine. The Project and the Layers are
stored into the Postgresql Server and all Persons could work with
it. Now my Problem is, that the Contents of the Layers must have
an unique ID. The ID is set by the default value at the attribute
form with<i> "maximum($id)+1"</i>. If two persons are working on
the QGIS System, the Problem is, that there are duplicated IDs,
because the IDs will not be stored immediately. Is there a
solution for this problem?</p>
<p>thank you for helping<br>
best regards</p>
<p>Alexander Klemm<br>
