Hi all
I just implemented workaround for exporting large compressed (gzip/bzip2) dumps. Created dumps may cause problems to some programs (but I didn't face any yet). So please test it and if you'll find any problems with created dumps $cfg['CompressOnFly'] should be FALSE as default. Your dump needs to be at least (memory_limit - 1.5M) * 2/3 big to activate new code.
