There are two excellent papers here:

Both were written by Dan Tow, a long term DBA who has my utmost respect. The papers pre-date this debate for several years and present a very coherent argument in support of hints.
They do not cover the psychological side of things. Telling users that PostgreSQL creators consider them dumber than a computer program is simply not a good idea if PostgreSQL is supposed to be an alternative to Oracle. It isn't. I am glad that we've ironed that out.
