How much overhead will you be adding to funnel them all through

No, only one function is sufficient. What else do you think of?

Yes. those are not directly associated with conversions.

The problem is that the new column is now part of pg_attribute so every
catalog/pg_attribute.h DATA() line has to be updated. Did you update
them all with 'false' in the right slot? Not sure what the chunks are.

It merrily renames the column in the child table (I tried it). When
