Sounds great. The only "strange" thing with PostgreSQL-Exceptions will 
then be that they have multilined messages, which is AFAIK uncommon, but 
not forbidden, in Java, but might eventually break logfile parsers. In 
my case i like the multiline exceptions. Another possibility would be to 
print all the information into a single line, and work a bit on the 
formatting to have this look good.

With best regards,
