default to something that's not valid for that datatype. Change them
to null or just empty them?
Hmmm, well variables can default to NULL too. The backend code tries to track those variables which default to NULL or to other values. For the rest, it defaults them to "". It then uses construct_md_array to generate the output string for type TEXTOID. Dunno if we can have nothing (an empty string) as valid TEXTOID output. I guess it's a limitation for this type. Let me see if we can do something here on the backend side...
