Re: [ADMIN] Size of logfiles
Hi! Just for other users who might have the same question: With default settings, postgres writes 3 WAL files. Each of them has the size of 16 mb. They are located at the data directory within the subdirectory pg_xlog. Cheers, Peter Am 22.05.2007 um 21:22 schrieb Peter Elmers: Hi Chris, Thanks for your fast reply. Indeed i ment the normal logfiles. But you point me to another question: I am just reading the manual regarding WAL, but until now, i found no hint about the default setting for the redo-logs(WAL).

Re: [ADMIN] Size of logfiles
Hi Peter, Thank you for your fast reply. Yes, indeed i ment the normal error- logfiles. But if i start postgres with -l what duration does the logfiles have?

That's easy: By default, postgres doesn't write a log file. There are about half a dozen ways to set this up, though. -- Peter Eisentraut http://developer.postgresql.org/~petere/ ---(end of broadcast)--- TIP 4: Have you searched our list archives? http://archives.postgresql.org ---(end of broadcast)--- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
