RowMetadata
The shape of a result: one ColumnMetadata per column, in the order the server returned them.
It is built once for a result, from the RowDescription that opens it, and every Row of that result shares it. Resolving the columns there rather than on demand is what keeps a result internally consistent: a reloadTypes() between two reads of the same result cannot leave two of its columns describing themselves against different catalogs.
A column whose type the dictionary does not describe fails at that point, with TypeException. Such a column could never have been decoded anyway - a type the catalog load did not see has no codec either - and failing on the description rather than on the first row that happens to carry a value makes it fail the same way every time.
