Okay, maybe I set it to high. I will try to find that out.
Maybe I should run 26 queries like these:
INSERT INTO table2 (my_col) SELECT DISTINCT my_col from table1 where my_cole
like 'a%'
So postgresql could use my index on my_col and store more data in memory. Do
you think that would be better?
Thank you,
Christian
