* db/INSTALL: Add parallel execution settings
hunk ./db/INSTALL 29
+#
+# Parallelism: As of PG 10 this does not really matter because we're
+# using serializable transactions by default.
+# Current box has 8 cpus.
+# Allow 4 workers per core: max_worker_processes=32
+# Use lots of parallelism, maxing out the cores
+# on any pararallel query: max_parallel_workers_per_gather=8
+# Allow 4 workers per core, per "user": max_parallel_workers=32
+
hunk ./db/INSTALL 49
