    I'm doing that now. Here is what I wrote in the report :

    Using prepared statements (important), Postgres beats MyISAM on "simple
selects" as they say, as well as complex selects, even with 1 thread.

    MyISAM caused massive data corruption : posts and topics disappear,
storage engine errors pop off, random thrashed rows appear in the forums
table, therefore screwing up everything, etc. In short : it doesn't work.
But, since noone in their right mind would use MyISAM for critical data, I
include this result anyway, as a curiosity.

    I had to write a repair SQL script to fix the corruption in order to see
how MySQL will fare when it gets bigger than RAM...
