I am trying to copy some Feature Classes into a Feature Dataset. But fail due to error "The output Feature Dataset is locked by another user".
The feature classes are on the same database, Enterprise Geodatabase using Postgresql.
I check on the enterprise geodatabase properties and I see some feature classes are locked using "shared mode". Strangely, no one is using it except me. The Feature Dataset should not be in Locked position because I just opened it and no processing is going on whatsoever.


What is the cause of this problem ?
How do I release the locks ? is it by restarting the Postgresql service ?
I am using ArcGIS Pro 3.1.0 and ArcGIS Enterprise Standard 11.0
thanks
