QGIS crashes when removing a postgis layer after renaming a column

[qgib]

Author Name: Giovanni Manghi (@gioman)
Original Redmine Issue: 8242
Affected QGIS version: master
Redmine category:data_provider/postgis

---

Add a postgis layer

rename a column (I used DB Manager)

remove the layer -> crash

please notice that after renaming the column, the table of attributes of the layer is empty. Refreshing the canvas does not help, it is necessary to add again the layer.

Not sure if it is a regression.
