Fields

name: String

columns: Vec<ColumnSchema>

hot_tier_bytes: Option<u64>

v6.7.2 — per-table hot-tier byte budget override. None falls through to the global SPG_HOT_TIER_BYTES setting; Some(n) overrides it for this specific table. Set via ALTER TABLE t SET hot_tier_bytes = X. Persisted in catalog FILE_VERSION 11+.

foreign_keys: Vec<ForeignKeyConstraint>

v7.6.1 — FOREIGN KEY constraints declared on this table. Engine maintains this in lock-step with spg-sql’s parser AST; the storage layer carries the on-disk shape so a catalog snapshot round-trips without external mapping. Persisted in catalog FILE_VERSION 13+. Older catalogs deserialise with an empty vec.

uniqueness_constraints: Vec<UniquenessConstraint>

v7.9.19 — composite UNIQUE / PRIMARY KEY constraints declared at the table level. Each entry’s leading column has a BTree index (created via the constraint), and INSERT path enforces the full-tuple uniqueness via a scan keyed by the leading column. Persisted in catalog FILE_VERSION 15+. Older catalogs (≤ 14) deserialise with an empty vec.

exclusion_constraints: Vec<ExclusionConstraint>

v7.39 (round 210) — EXCLUDE constraints declared at the table level. Enforced on INSERT/UPDATE by a full live-row scan re-checking each element’s operator (no equality index can answer overlap). Persisted in catalog FILE_VERSION 72+; older catalogs deserialise with an empty vec.

checks: Vec<CheckConstraint>

v7.13.0 — CHECK (<expr>) predicates declared on this table. Both column-level inline CHECK (…) and table-level CHECK (…) fold into this list. Each entry is the AST Expr’s Display form, re-parsed on every INSERT/UPDATE and evaluated against the candidate row. A false / NULL result rejects the mutation (PG semantics). Persisted in catalog FILE_VERSION 23+. Older catalogs deserialise with an empty vec. v7.39 (read01 round 48) — each entry now carries the user’s constraint name too (FILE_VERSION 60+).

partition_role: Option<PartitionRole>

v7.37.6-B — declarative partition role(sentori Epic 2 P0). None = 普通表(后向兼容,< v49 catalog 默认 None)。 Some(Parent { … }) = CREATE TABLE p (...) PARTITION BY RANGE (key_col) 父表 — 父表自己 rows 永远空,INSERT 在引擎层路由到命中的 child。 Some(Range { … }) = CREATE TABLE c PARTITION OF p FOR VALUES FROM (a) TO (b) 范围子表。 Some(Default { … }) = CREATE TABLE c PARTITION OF p DEFAULT 兜底子表。 持久化于 FILE_VERSION 49+。

policies: Vec<PolicyDef>

v7.39 (RLS) — CREATE POLICY objects on this table, independent of the row_security flag (PG stores policies even on non-RLS tables; they only take effect once RLS is enabled). Persisted in the policy appendix (FILE_VERSION 59+). Older catalogs deserialise with an empty vec.

row_security: bool

v7.39 (RLS) — ALTER TABLE … ENABLE ROW LEVEL SECURITY (PG pg_class.relrowsecurity). Fresh table = false.

force_row_security: bool

v7.39 (RLS) — ALTER TABLE … FORCE ROW LEVEL SECURITY (PG pg_class.relforcerowsecurity); subjects the table owner to RLS too. Fresh table = false.

owner: Option<String>

v7.39 (read01 round 57, ACL) — the role that owns this table: whoever ran CREATE TABLE (PG pg_class.relowner). The owner holds every privilege implicitly and is the only role that may ALTER / DROP it. None = an image written before FILE_VERSION 64, which predates roles entirely; those tables read back as owned by the login role.

acl: Vec<AclItem>

v7.39 (read01 round 57, ACL) — explicit GRANTs on this table (PG pg_class.relacl). EMPTY means “never granted”: PG leaves relacl NULL while only the owner’s implicit privileges apply, and materialises the whole list — owner’s default entry included — on the first GRANT. Once materialised it stays, even after every grant is revoked.
