Sorry, I guess I didn't sufficiently understand the issue. I don't
really use PL/Perl myself, but I would think there was some way to
return an array. In the docs, I see:
"Conversely, the return command will accept any string that is
acceptable input format for the function's declared return type. So, the
PL/Perl programmer can manipulate data values as if they were just text."
So if you declare the PL/Perl function to return text[], and return a
properly formatted array, e.g. something like
"{\"blah blah\",\"foo bar\",\"etc etc\"}"
it ought to work.
