-- Tests the different DROP commands for cstore_fdw tables.

-- DROP FOREIGN TABL
-- DROP SCHEMA
-- DROP EXTENSION
-- DROP DATABASE

-- cstore_fdw extension in default database (postgres). This has caused
-- different behavior between travis tests and local tests. Thus
-- 'postgres' directory is excluded from comparison to have the same result.
