But you're not running the least buggy version of the 7.4 branch. The 7.4 branch is up to 7.4.9. If you are runing 7.4.2 then you haven't installed all the updates supplied by Suse for their distribution (or Suse backports bug fixes from 7.4.9 to 7.4.2, which I kinda doubt) which means you likely haven't upgraded ANY of the packages that came with it, which means your system, if it is put on the internet, will likely be hacked within days, if not hours. I would recommend looking into at least 8.0. It's been out for a year, it's quite stable, and has many features like point in time recovery that make it a very good choice for production. > Thanks, Bob > > > > -----Original Message----- > From: Tom Lane [mailto:tgl@xxxxxxxxxxxxx] > Sent: Friday, February 10, 2006 10:16 AM > To: Given, Robert A > Cc: pgsql-admin@xxxxxxxxxxxxxx > Subject: Re: [ADMIN] Postgresql performance and tuning questions > > "Given, Robert A" <bgiven@xxxxxx> writes: > > We are beginning a project to use Postgresql 7.4.2 on zLinux SLES9 The > > > application of interest is uPortal 2.4.3. > > Why are you not starting with a reasonably up-to-date version of > Postgres? > > regards, tom lane > > ---------------------------(end of broadcast)--------------------------- > TIP 6: explain analyze is your friend
