Well, it was on the TODO list and people complained while porting their MySQL applications. We clearly made a mistake in the initial implementation. The question is do we fix it or continue with a different implementation. Because we have the separate LIMIT and OFFSET we can fix it while giving people a solution that will work for all versions. If we don't fix it, all MySQL queries that are ported will be broken. I assume it got on the TODO list because fixing it was the accepted solution. We can, of course, change our minds. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026
