Just to point out, FWIW, that the .NET Npgsql driver does indeed cache
RowDescriptions... The whole point of preparation is to optimize things as
much as possible for repeated execution of the query; I get that the value
there is much lower than e.g. doing another network roundtrip, but that's
still extra work that's better off being cut if it can be.
