pg_utility ?

Hello,

One of the things that came up during the pgconf.eu talk about REPACK,
proposed by Christoph Berg, is that adding another utility pg_repackdb
to run it from the command line adds more noise to an already noisy tool
neighbourhood.  He asked, how about we instead add a generic tool to run
utility commands?  So the user would be able to do things such as 

pg_utility vacuum -t tab1 -t tab2        # what vacuumdb does
pg_utility analyze -t tab1 -t tab2        # what vacuumdb -Z does
pg_utility vacuum analyze -t tab1 -t tab2    # what vacuumdb -z does
pg_utility cluster -t tab1 -t tab2        # what clusterdb does
pg_utility reindex -t tab1 -t tab2        # what reindexdb does

Each such tool would retain more or less its current behavior, i.e., its
ability to run things in parallel, to discover tables to operate on
based on circumstances, to silently ignore objects depending on the user
lacking specific privilege bits, and so on.

This way, instead of an entire pg_repackdb tool, we would add just a new
mode to pg_utility:

pg_utility repack -t tab1 -t tab2        # what pg_repackdb would do

Christoph, can you please confirm that this is approximately what you
had in mind?  Other names are of course possible.

I didn't immediately love this idea, but I'm not totally opposed to it
either, and perhaps it makes things better rather than adding yet
another very narrowly-focused tool.  Also, pg_ctl already kinda has a
somewhat similar facet with its "pg_ctl init" mode.

Thanks
