While writing slides for pgopen next week, I noticed that the JSON docs
on json_populate_record and json_populate_recordset contain this sentence:
A column may only be specified once.
IIRC we removed that restriction during development, so unless there is
a squawk I am going to simply remove that sentence where it occurs. Or
should we say something like:
If a column is specified more than once, the last value is used.
