And since 7.3 we have ganged WAL writes (c.f. the thread starting at
http://archives.postgresql.org/pgsql-hackers/2002-10/msg00331.php) which
IMHO is a better solution to the same problem. Maybe the code dealing
with commit_xxx parameters should just be removed.
Are you or is anybody else aware of benchmarks showing that group commit
via commit_xxx is still useful?
