Explicit locks in RedShift

I'm new to AWS Redshift and I wanted to know How i can implement my use-case. I have a Redshift table which gets lot of Inserts/Selects. In some cases I need to delete some data from that table. I don't want my Delete to impact other writes and reads. Can someone suggest what is the best locking mode available in Redshift to implement my use case. I don't want to end up with dadlocks and some locks hanging in my application. I tried without locks and I'm observing the following violation: Serializable isolation violation on table - 156300, transactions forming the cycle are: 6416378, 6416913 (pid:3770); Also I went through the Redshift cxplicit locks but couldn't find any Official documentation for the same. I know that Redshift is a wrapper on PostgreSQL, so can I use that documentation for implementing?
