I found an error message in pgbench is quite confusing. pgbench -S -M extended -c 1 -T 30 test query mode (-M) should be specified before any transaction scripts (-f or -b)
Since there's no -f or -b option is specified, users will be confused. Actually the error occurs because pgbench implicitly introduces a built in script for -S. To eliminate the confusion, I think the error message should be fixed like this: query mode (-M) should be specified before transaction type (-S or -N) or any transaction scripts (-f or -b) Patch attached.
