If a function is marked parallel-safe but internally calls parallel-restricted or parallel-unsafe functions, it wasn't really parallel-safe in the first place. So I think that if inlining introduces a parallel hazard, the user has mislabeled some functions and any resulting injury is self-inflicted. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
