Expand description
Change — one entry in a ChangeSet.
A Change describes a structural difference between a target catalog and
a source catalog at the level of a top-level object (schema, table, index,
sequence). Per-column / per-constraint operations live inside the
AlterTable variant as a list of
TableOpEntry; per-field sequence updates
live inside AlterSequence as
SequenceOpEntry.
