Doing some forensic work on a Postgres 9.5 database that is in testing with only 19 relations and over 100,000 sequences. Once this database goes live, it could see in excess of 1 Million sequences created due to the complexity of the application. There are obvious risks such as pg_dump issues and slow response when scanning catalog table for info. But, are there any serious issues that can show up from this situation? I know theoretically, postgres can have unlimited tables in a database. But, I am looking for some realistic worse case scenarios in an environment like the one described.
