Jan-Henrik,
Found some time today to do more testing on a problem I was still having with the mysql driver (the postgres driver is kicking ass).
I suspect there is still a problem in ensureCapacity (or it's consumers). I'm attaching a small program that will reliably reproduce this.
Looks like strings from the /first/ row (and only the first row) retrieved from a resultset are still being truncated at 256 char length.
tested against yesterdays svn-rev.
thanks,
