ERROR: cannot drop table TABLE_NAME_updating because other objects depend on it

[murtyk]

Version 0.1.2

We have been using PostgresToRedshift.update_tables method to copy tables from PG to Redshift every day since August 2017 and never had a problem. Suddenly we got this error:

ERROR: cannot drop table TABLE_NAME_updating because other objects depend on it
HINT: Use DROP ... CASCADE to drop the dependent objects too.

We are bit lost since no code changes mode for a long time and can't figure out what is causing this error.

Has any one encountered this?
