Hi!
Very first post in this arena 
We have store all our QGIS projects to PostgreSQL database. I see that QField documentation recommend to use Relative Paths in QGIS projects. It seems that QGIS is changing Relative Paths -configuration when project will be stored to PostgreSQL database: Set paths to "Relative" after saving a QGIS project from PostgreSQL/PostGIS onto a local drive 路 Issue #61014 路 qgis/QGIS 路 GitHub
When I will package now my QGIS project (from PostgreSQL), exported QGIS project will have absolute paths.
I have two (2) workarounds: modify Abs=>Rel path just before packaging to Qfield or change afterwards exported QGIS project file paths from Abs => Rel. Both workarounds are error-prone.
Any suggestion or should I create feature request?
Rgs,
