<p>Hi Alex,</p>
<p>Thank you for your reply.</p>
<p>In my case, the data resides in Postgis, not in Geopackage.</p>
<p>But if I understand you correctly, then Geopackage imposes it's limit on QGIS in general, aka other providers as well - right?</p>
<p>Thanks,<br />Andreas</p>

<div dir="auto">I believe that comes from the geopackage fid limitations. For that reason, I never use the fid field as an actual id. That's my workaround.

<p>Hi,</p>
<p>We have a problem with the merge tool.</p>
<p>We have a relatively complex data model with lots of relations. We want to use the merge tool with this data.</p>
<p>The merge tool allows to carefully choose which attributes should end up in the merged feature. This works fine, except for the feature ID.</p>
<p>QGIS stubbornly insists on having to create a new feature ID after the merge - and is not reusing the feature ID of the original feature we selected as the "master" feature in the merge tool.</p>
<p>This is a huge problem - because after the merge we loose all relations, because the feature ID has changed.</p>
<p>Do you know any work around? Would we be able to fix this behaviour in a future QGIS release?</p>
<p>Thanks for the discussion,</p>
<p>Andreas</p>
