Hmm, from a read of the manual and the code, I can't really tell if HSQLDB
supports structs. Lots of basic enum definitions, seemingly know explicit code
to support it, and not mentioned really in the manual.
Would you be OK merging this as-is and pursuing the high-level test later?
Since it is higher risk; maybe I spend an hour on it and turns out not to be
supported.
