An example for suddenly required quotation marks, this time not on an FK field as lastLogin is of type DateTime. Not sure what that is about.

An example for suddenly required quotation marks, necessary only on the FK field "favToy", not on the others.

Same for Line 71

What if you put the rest in quotations for consistency? Does it break the test?

This is so weird 🤔 Possibly, this has to do with mixing cases. If the column name uses mixed case, it must be quoted. But that's just a wild guess.

Changing the line to this: sql"""SELECT "species", "favToy", "id" FROM "Pet" WHERE id = $1"""
Still works perfectly fine.

An observation I made though, is that this:
sql"""SELECT "sPecies", "favToy", "id" FROM "Pet" WHERE id = $1"""
Will cause the test to fail while this:
sql"""SELECT sPecies, "favToy", "id" FROM "Pet" WHERE id = $1"""
works perfectly fine.

I'm getting the impression that not only are suddenly the quotation marks sometimes mandatory, they cause the column names to suddenly be case-sensitive.

toyRow = get dbConn.getRow(sql"""SELECT price, id FROM "Toy" WHERE id = $1""", pet.favToy.id)

check personRow == @[?"Bob", ?pet.id, ?person.id]
