Method RunCore passes 'UpdateExpression' as the paramName argument to a ArgumentException constructor. Replace this argument with one of the method's parameter names. Note that the provided parameter name should have the exact casing as declared on the method. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca2208)

In virtual/interface member RelationalUpsertCommandRunner.ShouldMapColumn(IProperty), rename parameter property so that it no longer conflicts with the reserved language keyword 'Property'. Using a reserved keyword as the name of a parameter on a virtual/interface member makes it harder for consumers in other languages to override/implement the member.

In externally visible method 'bool PostgreSqlUpsertCommandRunner.ShouldMapColumn(IProperty property)', validate parameter 'property' is non-null before using it. If appropriate, throw an 'ArgumentNullException' when the argument is 'null'. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1062)
