Hello Nathan,

I’ve noticed liquibase do not drop sequences in postgres in case dropFirst is true.  
(tested on postgres 9.3, liquibase 3.1.1, 3.3.2)

in case it is a bug I can submit a bug request to jira.

as a workaround one can add the following to the begin of the db-changelog.sql file  
–changeset youName:1 context:test failOnError:true  
DROP SEQUENCE IF EXISTS your\_sequence;

PS Thank you for supporting this great project!

Regards,  
Vitaliy
