Stop Using SERIAL in Postgres

In a recent article on Naiyer Asif's blog, the author discusses the challenges associated with using the SERIAL data type in PostgreSQL databases. He recommends switching to types like BIGSERIAL or explicit sequences, which allow for better management of sequential numbers. Key disadvantages of SERIAL include issues with transparency and difficulties with synchronization during replication processes. Asif also highlights potential errors arising from conflicts when many operations are performed in parallel. In conclusion, the author emphasizes that selecting the right data type can enhance application performance and simplify future changes to the database structure.
