BE-456: HashQL: Entity type model enrichment and graph store query extensions by indietyp · Pull Request #8524 · hashintel/hash

indietyp · 2026-03-08T15:46:10Z

🌟 What is the purpose of this PR?

Enriches the HashQL entity type model to match the full database schema, extends the graph-store SQL query builder with new expression types needed by the postgres compiler, and adds a database migration for the continuation composite type. This is the foundation layer for the postgres translation stack (BE-457, BE-306).

🔍 What does this change?

hashql-core:

Adds IdSnapshotVec, a typed-ID-indexed vector with transactional snapshot/rollback support (used by the postgres compiler for scoped state)
Expands the entity type definition with TemporalInterval, EntityTemporalMetadata, Confidence, provenance types, EntityMetadata, and LinkData fields to match the full database schema. Previously only EntityId, EntityRecordId, and partial LinkData were modeled.
Adds edition_id and ontology_type_ids symbols

graph-postgres-store query builder:

New expression types: FieldAccess (composite field extraction), JsonAgg, Constant::Null, Constant::U128, UnaryOperator::IsNotFalse
New cast targets: JsonB, Continuation, Numeric, Int, BigInt
Unnest now accepts multiple expressions (UNNEST(a, b, c))
SelectStatement gains OFFSET support
Convenience methods: .cast(), .not() and .grouped() now take self
Alias type changed from &'static str to Identifier for consistency
Visibility: mod postgres and mod table made pub for use by the HashQL postgres compiler
Unit tests for all new expression types

Database migration (v010__query):

Creates the continuation composite type: (filter boolean, block int, locals int[], values jsonb[]). This is the row type returned by compiled filter subqueries; the interpreter reads .filter to decide row inclusion and .block/.locals/.values to resume multi-block CFGs.

hashql-eval:

Reworks graph/read/path.rs to handle the expanded entity field structure
Scaffolding in lib.rs and error.rs for the postgres module (filled in by BE-306)

Test output updates:

~55 files of updated .jsonc/.stdout/.stderr fixtures across eval (graph/read), HIR (lower/checking, specialization, graph-hoisting), and MIR (reify, inline) test suites, all cascading from the entity type changes

Pre-Merge Checklist 🚀

🚢 Has this modified a publishable library?

This PR:

does not modify any publishable blocks or libraries, or modifications do not need publishing

📜 Does this require a change to the docs?

The changes in this PR:

are internal and do not require a docs change

🕸️ Does this require a change to the Turbo Graph?

The changes in this PR:

do not affect the execution graph

⚠️ Known issues

The entity type model still does not cover every field in the database schema (e.g., property_metadata inner structure is opaque). Fields are added as needed by the postgres compiler; remaining gaps will be filled incrementally.

🛡 What tests cover this?

IdSnapshotVec has doc tests and inline unit tests covering push/set/rollback/nested snapshots
New graph-store query builder tests for FieldAccess, JsonAgg, Null, U128, IsNotFalse, UNNEST with multiple args, cast types, and OFFSET
Existing compiletest suites (eval graph/read, HIR lowering, MIR reify/inline) with blessed output updates

❓ How to test this?

cargo nextest run -p hashql-core
cargo nextest run -p hashql-eval
cargo nextest run -p hash-graph-postgres-store --lib

PR Summary

Medium Risk
Medium risk because it introduces a new Postgres composite type migration (continuation) and expands the SQL query builder/HashQL path model, which can affect query compilation and database compatibility.

Overview
Adds a database migration (and store migration) creating the continuation composite type used by query compilation.

Extends the Postgres query builder with new SQL constructs (e.g., FieldAccess for composite-field extraction, jsonb_agg, multi-arg UNNEST, new constants/types/casts, OFFSET, and Identifier-based aliases) and broadens public exports needed by downstream compilers.

Enriches HashQL’s entity type model to include metadata/temporal/provenance/confidence/encodings and updates graph read path resolution plus a large set of compiletest fixtures to reflect the new entity.metadata.record_id... access pattern.

Autofix Details

Bugbot Autofix prepared fixes for both issues found in the latest run.

✅ Fixed: Misleading enum variant name for jsonb_agg function
- Renamed Function::JsonAgg to Function::JsonbAgg and updated all internal usages/tests to match the emitted jsonb_agg(...) SQL.
✅ Fixed: Multiple new symbols defined but never referenced
- Removed the eight unreferenced symbol definitions from sym.rs to eliminate dead entries and duplicate provenance naming.

🤖 Augment PR Summary

Summary: This PR enriches the HashQL entity type model to better reflect the full graph database schema, and extends the Postgres query-builder/AST to support additional SQL constructs needed by the HashQL→Postgres compiler.

Changes:

Adds a new DB migration creating a continuation composite type used as the return row type for compiled filter subqueries.
Introduces IdSnapshotVec, a typed-ID-indexed vector with snapshot/rollback support for scoped compiler state.
Expands ::graph::types::knowledge::entity with temporal metadata, confidence/provenance, enriched link data, entity metadata, and encodings.
Extends the graph Postgres query builder with composite field access, jsonb_agg, additional constants/casts, multi-arg UNNEST, and OFFSET.
Updates HashQL eval graph path resolution to traverse the new entity field structure.
Blesses updated UI/compiletest fixtures across eval/HIR/MIR to reflect the new entity model.

Technical Notes: Query builder aliasing is standardized on an Identifier type; new expression/unit tests cover the added SQL features.
