Expand description

v7.17.0 — catalogued SEQUENCE. PG semantics: a counter object returning monotonically increasing values via nextval(name). last_value is the most recent value handed out; is_called is false until the first nextval/setval. Stored separately from tables in the catalog.

Fields§

§name: String§data_type: SequenceDataType

Data type — narrows the i64 range. PG default BIGINT.

§start: i64§increment: i64§min_value: i64§max_value: i64§cache: i64§cycle: bool§owned_by: Option<(String, String)>

OWNED BY target — (table, column) or NONE.

§last_value: i64

Most recently handed-out value. Meaningless when is_called == false; in that case the NEXT nextval will return start.

§is_called: bool§owner: Option<String>

v7.39 (read01 round 60) — the role that ran CREATE SEQUENCE. None = an image written before FILE_VERSION 66, which predates sequence owners.

§acl: Vec<AclItem>

v7.39 (read01 round 60) — explicit GRANTs on this sequence. A sequence’s meaningful privileges are SELECT (currval), UPDATE (setval) and USAGE (nextval).
