It looks to me like sqldf is unaware of the rules about identifier
case-folding in Postgres. That column would come back named
"broedselid", but it's probably looking for "BroedselID".
Or possibly it's expecting the qualifier "dbo_tbl_Broedsels."
to be included in the returned column name. Either way, you
need to bug sqldf's authors to fix it.
