The documentation states "A block containing an EXCEPTION clause is
significantly more expensive to enter and exit than a block without one.
Therefore, don't use EXCEPTION without need."
Our application developers would like to get back a simple code ( a
number) for any error that indicates what it is, and possibly a message.
So, as we would with Oracle we wanted to code in exception handlers to
do this, but the documenation has us concerned. Is putting exception
handlers into the pgsql code really a big performance hit?
Thanks,
