Oil pressure range

What is your question?

Got my engine on an Accord 2011 V6 sedan with 130000km/81000mi checked and they told me oil pressure is only 45psi and engine needs to be changed. I was surprised since engine runs well. What is the acceptable pressure range for an older car and if the cylinder pressure is good, should I simply get oil pump changed? Thank you!

What makes this problem better or worse?
