Strange. For some reason I've never seen the original mail. Seems that's
just another of those typical usa.net mail losses. Could someone please
forward it to me. Thanks.

Sorry, but that's incorrect syntax. What you want to do is:

func()
{
printError();
return FAILURE;
}

EXEC SQL WHENEVER SQLERROR DO func();

BTW there is a function defined in libecpg named sqlerror() that prints a
clear text error message.
