jrgemignani opened a new pull request, #2446:
URL: https://github.com/apache/age/pull/2446
The vertex/edge staging copies in create_subgraph() generated new graphids
with nextval(%L), which binds the sequence as a string literal and invokes the
nextval(text) overload. That re-resolves the schema-qualified sequence name on
each call.
Cast the literal to regclass (nextval(%L::regclass)) so the sequence is
resolved once to its OID, matching how AGE defines its label id defaults
(nextval('schema.seq'::regclass)). Applied to both the vertex and edge staging
queries, in sql/age_subgraph.sql and the identical body in the
age--1.7.0--y.y.y.sql upgrade template so the upgrade-path catalog comparison
still matches.
Behavior is unchanged; all 38 regression tests pass against PostgreSQL 18.
Addresses Copilot review feedback on apache/age#2441.
