8Kb or 4Kb ext4 filesystem page size

[Alexandre hadjinlian guerra <alexhguerra@xxxxxxxxx>]

Hi

Given that postgres uses 8Kb pages, im wondering why i couldnt see any tests at all which would format ext4 partition to 8Kb pages. Im about to do some tests, but any knowledge about such lack of tests on the internet makes me wonder if im looking poorly or just lack of testing. besides, i do ask if the following link remain true given XFS and EXT4 evolution since 2015
