Fields in generated avro schema are always lower-cased

When importing from Postgres (and I guess, from other databases) to Avro, the column names that I give to fields are not case-sensitive and always appear lower cased in avro schema.
E.g. if I provide a query like:

select account_id as accountId from accounts

in avro schema there is the "accountid" field instead of "accountId"

Is it something that can be easily fixed?
