Dear PostgreSQL Creators, I am frequently using PostgreSQL server to manage the data, but I am stuck ed now with a problem of large objects deleting, namely it works too slow. E.g., deleting of 900 large objects of 1 Mb size takes around 2.31 minutes. This dataset is not largest one which I am working with, e.g. deleting of 3000x1Mb objects takes around half an hour. Could you, please, give me a few advices what do I have to do to improve the deleting time? (i've tried to extend the memory server uses, but results are the same) Best regards!
