I can't think of any difference between 7.3 and 7.4 that would create
a problem of that sort where there was none before.  For that matter,
since Postgres runs nonprivileged it's hard to see how it could create
a priority problem in any version.  I thought the previous suggestion
about added use of hashtables was a pretty good idea.  We could
confirm or disprove it by looking at EXPLAIN output.
