configmap size error with sql backend #345

Hello,

We are currently using postgres AWS RDS database instance to utilize helm sql backend feature which should support helm release larger than 1mb in size. However, today when we executed a test we received an error saying "* ConfigMap "nameremoved" is invalid: []: Too long: must have at most 1048576 bytes".

The installation has created database , schema and tables on RDS instance which means it's able to connect but fails during installation.
Fyi, the size of our configmap file is 2Mib.
