Hi hackers, This patch series implements the TODO in predicate.c that suggests adding ratio-based predicate lock limits.
The series is split into two logical commits: 1. Core implementation of the GUC variables and predicate lock logic 2. Comprehensive regression tests Patch overview: - Adds max_predicate_locks_per_relation_ratio and max_predicate_locks_per_page_ratio GUCs - When ratios are > 0, calculates lock limits based on relation size estimates - Maintains full backward compatibility (default 0.0 = use existing fixed limits) - Includes complete regression test coverage This addresses the TODO comment in MaxPredicateChildLocks() for more intelligent lock allocation in mixed workloads. Looking forward to your review! ArkadySkv
