The debug messages that merely print StartTransactionCommand, CommitTransactionCommand, ProcessUtilty, or ProcessQuery with no additional details seem to be useless. Get rid of them. The transaction status messages produced by ShowTransactionState are occasionally useful, but they are extremely verbose, producing multiple lines of log output every time they fire, which can happens multiple times per transaction. So, reduce the level to DEBUG5; avoid emitting an extra line just to explain which debug point is at issue; and tighten up the rest of the message so it doesn't use quite so much horizontal space. With these changes, it's possible to run a somewhat busy system with a log level even as high as DEBUG4, whereas previously anything above DEBUG2 would flood the log with output that probably wasn't really all that useful. |
