Yes, because it doesn't contain the three letters "log".
We have the two precedents "pg_subtrans" and "pg_multixact", so
unless we want to get into renaming those too, I think "pg_trans"
and "pg_xact" are really the only options worth considering.
Personally I'd go for "pg_trans", but it's only a weak preference.
