Re: LWLock SerializableFinishedList - Mailing list pgsql-general

Also reviewing if we really need SERIALIZED and could instead use READ COMMITTED. Would that be likely to mitigate against this happening?

PostgreSQL can NOT  go below READ COMMITTED in transaction isolation levels.  Read Committed is the default mode for all transactions in PostgreSQL 

https://www.postgresql.org/docs/17/transaction-iso.html  

Unless there is a very specific need for serializing transactions such as financial calculations or updating and calculating  the remaining number of tickets to sell for a concert,  Serialization adds a lot of overhead for not much gain..
