Hi, I noticed one thing: autovacuum_max_parallel_workers is initialized to 0 in globals.c, but its GUC default (boot_val) is '2' in guc_parameters.dat. While GUC overrides it on startup, this mismatch may cause confusion. Perhaps we should modify this to match the approach for max_parallel_workers.
