[GENERAL] Merge - Insert Select

What is the best practice for doing an INSERT...SELECT statement for new 
values only.  Existing values must be excluded from the insert.

Does postgres have a MERGE statement ala Oracle?

I have found examples online for INSERT...ON CONFLICT DO NOTHING, but 
all of those examples use VALUES statements, which is not the scenario 
that I have.

Thanks for your help!

Sue
