MuhammadTahaNaveed opened a new pull request, #2303:
URL: https://github.com/apache/age/pull/2303
- Introduce vertex and edge as pg composite types
vertex: (id, label, properties)
edge: (id, label, start_id, end_id, properties)
- Property access (a.name) now directly uses a.properties for
agtype_access_operator instead of rebuilding via _agtype_build_vertex/edge
- Optimize accessor functions (id, properties, label, type, start_id,
end_id) to use direct FieldSelect on composite types instead of agtype functions
- Add casts: vertex/edge to agtype, vertex/edge to json
- Fix label_name specific routine to use cache instead of ag_label scan
- Write/update clauses have executors strictly tied to agtype, due to which
the variables after any write/update clause are carried forward as agtype.
- Allows users to completely skip agtype build functions and return
vertex/edge for pure read queries.
- Change _label_name to return agtype since record comparisons are not
allowed with cstring. Consequently, _agtype_build_vertex/edge now accept agtype
as label.
- Fix MERGE clause type mismatch when accessing properties from previous
MATCH clauses by wrapping columns with agtype_volatile_wrapper before namespace
lookup.
- Update expression index in pgvector.sql, since now it uses raw properties
column instead of _agtype_build_vertex/edge.
- Add regression tests
