An interesting point is that until recently, crashme said that the
postgresql backend crashed on very large queries. The actual problem was
that postgresql has NO LIMIT to query size, and the crashme script would
keep feeding the postgresql backend larger and larger amounts of query
until the internal buffer of the crashme script overran.
This failure was attributed to postgresql when it was, in fact a bug in
the crashme script.
This is not an isolated behaviour of crashme. It's a quick dirty hack job
designed to show the differences between MySQL and all the other
databases. If it was truly comprehensive (i.e. SQL92 spec testing) there
would be hundreds of failure points for MySQL. but it isn't. It tests
only those things that are good in MySQL against other databases (for the
most part, there is some token effort at including a few things MySQL
doesn't do).
