postgres wont do preparedstatements

[Jan-Henrik Haukeland]

Ps. Also run with the debug flag set, ZBDEBUG = TRUE; Not that we  
output much debug info, but you may be lucky. Since postgres work with  
pool.c this sounds strange, though pool.c of course may not test all  
cases. Please double check how you call libzdb if you have not already  
done so first.

Maybe you have a dbmail repository we can look at for the  
implementation?
