= SQL REPEATABLE READ isolation level
{c}
Vs <SQL SERIALIZABLE isolation level> on <PostgreSQL>: https://dba.stackexchange.com/questions/284744/postgres-repeatable-read-vs-serializable
<nodejs/sequelize/raw/parallel_create_delete_empty_tag.js>{file} is an example which experimentally seems to be solved by `REAPEATABLE READ`, although we are not sure that this is truly the case and why. What is clear is that that example is not solved by the <SQL READ COMMITTED isolation level>.
In <PostgreSQL>, this is the first isolation level which can lead to <postgreSQL serialization failures>, this does not happen to <SQL READ COMMITTED isolation level> in that <DBMS>. You then have to retry the transaction.
