Re: pgbench - adding pl/pgsql versions of tests

I will address the comments here over this coming weekend.

I think that in addition to current "tpc-b like" test we could also
have more modern "tpc-c like" and "tpc-h like" tests

And why not any other "* -like" from the rest of TPC-*, YCSP, sysbench, ... :)

though maybe not as part of pg_bench but as extensions ?
