Can i increase the maximum size for a JSONB record in postgres?

In Postgres 9.5.4 i'm getting the following error when trying to write a 500MB JSON file.

{ error: total size of jsonb array elements exceeds the maximum of 268435455 bytes

PSQL Output:

Question: Is there a way to increase the amount of data i can store? If not what other options should i look at?
