A change to a single aggregate (identity = (qname, arg_types)).

Variants

Create(Aggregate)

CREATE AGGREGATE …

Replace

DROP AGGREGATE old; CREATE AGGREGATE new; — any structural change (state_type/sfunc/finalfunc/initcond) has no in-place ALTER.

Fields

from: Aggregate

As it exists in the target (live).

to: Aggregate

As it should exist in the source.

Drop

DROP AGGREGATE name (argtypes);

Fields

qname: QualifiedName

Aggregate name.

arg_types: Vec<ColumnType>

Argument types (identity).

AlterOwner

ALTER AGGREGATE name (argtypes) OWNER TO owner;

Fields

qname: QualifiedName

Aggregate name.

arg_types: Vec<ColumnType>

Argument types (identity).

owner: Identifier

Desired owner.

CommentOn

COMMENT ON AGGREGATE name (argtypes) IS …;

Fields

qname: QualifiedName

Aggregate name.

arg_types: Vec<ColumnType>

Argument types (identity).

comment: Option<String>

New comment (None clears it).

Trait Implementations

impl Clone for AggregateChange

fn clone(&self) -> AggregateChange

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AggregateChange

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AggregateChange

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for AggregateChange

impl PartialEq for AggregateChange

fn eq(&self, other: &AggregateChange) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AggregateChange

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
