What versions of Ruby and ruby-postgres are you using? Did you use
exactly the code I posted or did you do something different? The
only way to get a PGrow object (other than building it yourself)
is from PGresult#each or some method that calls it, so this won't
work:
conn = PGconn.new('dbname=test')
result = conn.exec('SELECT 1 AS x')
row = result[0] # returns an Array
puts row['x'] # raises TypeError
but this does work:
row = result.to_a[0] # returns a PGrow
puts row['x']
I'm not sure if the PGrow behavior is version-specific. I don't
see it mentioned in the ruby-postgres ChangeLog, so I'd have to dig
a little more to find out.
