Hi all. It's not clear to me whether it's faster to check error conditions before actually executing some statements or to add error trapping code to "react" to errors. The documentation states that the former should be faster than the latter. Which is more or less the same as I can experience in C++ with try/catch constructs. But from time to time I read something on this very mailing list that makes me think the reality is different. Is there any authoritative, and possibly proven, answer to this topic? -- Vincenzo Romano at NotOrAnd Information Technologies Software Hardware Networking Training Support Security -- NON QVIETIS MARIBVS NAVTA PERITVS -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
