Add an
--expect-oneflag to thepgroll migratecommand to allow the command to fail if there is more than one outstanding migration.From the documentation added in this PR:
By default,
pgroll migratewill apply all unapplied migrations. However, it may sometimes be desirable to only apply a single migration to ensure that an existing version schema is not removed by a sequence of migrations. In this case, running:will cause the command to fail if more than one unapplied migration is detected.
