You can do that.

Is there any "offical" way to do this?

There is a "COPTX" command line option that you can pass on the ant command
line to change the compiler optimization flags, but the "configure" options
are not change-able from ant.  I think your best bet is to do what it sounds
like you've already done, modify the postgres/build.xml file to change the
configure options.

Absolutely.  The process is the same for those that are bundled - edit
postgres/build.xml and recompile.

You bet - happy to help, your input is valuable.

BTW - your benchmark data could be helpful to others, I wonder how we can
post it.  You could use the bizgres forum at www.bizgres.org I suppose.
