Thanks, I also prefer "wal_level_insufficient". To me
"primary_wal_level" sounds more along the lines of a GUC name than the
conflict_reason. The other names that come to mind are
"wal_level_lower_than_required", "wal_level_lower",
"wal_level_lesser_than_required", "wal_level_lesser" but I feel
"wal_level_insufficient" sounds better than these. Having said that, I
am open to any of these or better options for this conflict_reason.
