Instances are provided for tuples up to 10 elements and lists of any length.
</p><p>Note that instances can be defined outside of postgresql-simple, which is
often useful. For example, here's an instance for a user-defined pair:
</p><pre>data User = User { name :: String, fileQuota :: Int }
instance <code><a href="Database-PostgreSQL-Simple-FromRow.html#t:FromRow">FromRow</a></code> User where
fromRow = User <$> <code><a href="Database-PostgreSQL-Simple-FromRow.html#v:field">field</a></code> <*> <code><a href="Database-PostgreSQL-Simple-FromRow.html#v:field">field</a></code>
</pre><p>The number of calls to <code><a href="Database-PostgreSQL-Simple-FromRow.html#v:field">field</a></code> must match the number of fields returned
in a single row of the query result. Otherwise, a <code><a href="Database-PostgreSQL-Simple-FromField.html#v:ConversionFailed">ConversionFailed</a></code>
exception will be thrown.
</p><p>Note that <code><a href="Database-PostgreSQL-Simple-FromRow.html#v:field">field</a></code> evaluates it's result to WHNF, so the caveats listed in
mysql-simple and very early versions of postgresql-simple no longer apply.
Instead, look at the caveats associated with user-defined implementations
of <code><a href="Database-PostgreSQL-Simple-FromField.html#v:fromField">fromField</a></code>.
