Обсуждение: Read-only postgres instance
Hi, guys! I want to completely disallow postgres to write WAL and turn it to read-only instance WAL-compatible with another instance. It is guarantied that there will be no write queries to the server, but I need to be sure about WAL. Is it possible? -- Best regards, Vladimir Protasov.

Have you considered setting it up as a hot standby, but then not feeding it a WAL stream? -Kevin

Creating a temp table is not a read-only operation. On Aug 9, 2011, at 11:19 AM, pasman pasmański wrote: > What with queries need temporary tables? -- Scott Ribe scott_ribe@elevated-dev.com http://www.elevated-dev.com/ (303) 722-0567 voice
