<p>Hi,</p>
<p>Here is a quite interesting new feature in PostgreSQL 12:</p>
<p><a href="https://www.2ndquadrant.com/en/blog/generated-columns-in-postgresql-12/">https://www.2ndquadrant.com/en/blog/generated-columns-in-postgresql-12/</a></p>
<p>It is similar to virtual columns in QGIS.</p>
<p>I suspect that users will want to use that new column type. What does this mean for QGIS? I guess QGIS will have to detect this new column type in the future and mark it as "immutable". So other columns are read/write, but generated columns will be read only. Does QGIS already support a concept like this where some columns are read/write and others not?</p>
<p>Greetings,</p>
<p>Andreas</p>
