this seems backward, as far as the pk remain meaningless they're easier to port around, not harder. it's once you give them a meaning then trouble starts (for example you can't change the slug down the road if the title changes) and with integer keys the worst that can happen is that the sequence is not in the backup so after a restore you need to have the p sequence restart from the previous max id + 1; meanwhile with slug built off user entered data a change in collation can really screw up your day, unless you want to mangle all texts into basic ascii, and SO doesn't https://stackoverflow.com/questions/41102371/sql-doesnt-differentiate-u-and-ü-although-collation-is-utf8mb4-unicode-cia https://stackoverflow.com/questions/41102371/sql-doesnt-diff...
