Performance of Postgresql Merge vs Insert & Update statements

I would like to know will my performance of my SP’s written in postgresql is going to improve if I move my insert and update statement to the merge statement or it will hamper the performance.

Also if you can provide any official/trustworthy link on the same would be really appreciable.

Just FYI, I am using Postgresql in AWS Aurora Serverless.

Hi there,

The main benefit of using a MERGE statement is that it offers some convenience over the traditional INSERT and UPDATE statements as you don’t have to worry about transactions with error handling.

However, if you are mainly after performance, then it is best to stick to INSERT and UPDATE statements.

Of course, it is best to test this for your application-specific needs and figure out how it affects your queries that might be specific to your application and data.

Hope that this helps!

Best,

Bobby
