PostgreSQL Driver

• Runs migrations in transcations. That means that if a migration failes, it will be safely rolled back.
• Tries to return helpful error messages.
• Stores migration version details in table schema_migrations. This table will be auto-generated.

Usage

migrate -url postgres://user@host:port/database -path ./db/migrations create add_field_to_table
migrate -url postgres://user@host:port/database -path ./db/migrations up
migrate help # for more info

# TODO(gemnasium): thinking about adding some custom flag to allow migration within schemas:
-url="postgres://user@host:port/database?schema=name"
