Afternoon. I was able to make the necessary changes to my base needed to migrate win_pg12 to debian pg14.
But there is a new problem, which was not there at the initial stage so I checked:
win_pg12:
-> Index Scan using index_class_tree_full on class c (cost=0.28..2.50 rows=1 width=235) (actual time=0.030..0.032 rows=1 loops=1)
Index Cond: (id = 650)
debian_pg14:
-> Index Scan using index_class_tree_full on class c (cost=0.28..2.50 rows=1 width=235) (actual time=842.795..842.796 rows=1 loops=1)
Index Cond: (id = 650)
I'm wondering where to dig next...
