I am working on a patch for 8.2 for this: * Add transaction_timestamp(), statement_timestamp(), clock_timestamp() functionality Current CURRENT_TIMESTAMP returns the start time of the current transaction, and gettimeofday() returns the wallclock time. This will make time reporting more consistent and will allow reporting of the statement start time. -- Bruce Momjian http://candle.pha.pa.us SRA OSS, Inc. http://www.sraoss.com + If your life is a hard drive, Christ can be your backup. +
