I have searched in many postgres blogs for Sequential UUID generation, which can avoid Fragmentation issue.
I did a POC(in postgres) with sequential UUID against Non sequential which has shown lot of different in space utilization and index size. Sql server has "newsequentialid" which generates sequential UUID. I have created C function which can generate a sequential UUID, but I am not sure how best I can use that in postgres.
I would really like to contribute to Postgres, If I can. Please let me know your thoughts or plans regarding UUID generation.
