Thanks, I spent some time describing the feature with documentation. A condensed description of the GUC is in the runtime-config file. Feature description has spread between TransformOrExprToANY and generate_saop_pathlist routines. Also, I've made tiny changes in the code to look more smoothly. All modifications are integrated into the two new patches.
Feel free to add, change or totally rewrite these changes.
I'm going to review and revise the patch.
One question I have yet.

Why do we limit transformation for these types? Also, it doesn't seem the current code restricts anything except composite/record.
