ruby on rails - Postgres throws error when running import from activerecord-import gem -

i switched postgres in development , next error breaks test case:

pg::error: error: column "id" of relation "assets_content_nodes" not exist : select pg_get_serial_sequence($1, $2)

same error happens in development , production environments not show stopper , not impact import. assets_content_nodes bring together table , i'd rather not add together 'id' column. ideas why may happening?

this fixed in activerecord-import -v0.3.1 (or perchance before version, broken in 0.2.11 , earlier). no longer need id column on table import.
