You are right, it wasn't. I have 2 datasets, one containing 12 mil entries
and the other 14 mil entries. I accidentally used the one with 12 mil
entries in that table which actually only contains 7000~ entries for that
sql query.
For now I have tested the 12.6 Postgres with default values and it finished
in 12 seconds. I'll do some thorough testing and let you know once I
finish, sorry for the confusion.
