Re: [Pgpool-general] Pgpool-II and Slony-I : query lag, sequences and stored procedures need help

Thanks for replying! I do not use autoincrement or serial because the application AS IS doesn't use it. Although I share your approach, the project I am currently managing uses its own approach to assign primary keys. For the sake of clarity I write down the stored procedure and the

Is there a way to make it throw SELECTS only to the slave/s. backend_weight0 = 0 should do what you want. I'm still confused about the md5 passwords in master/slave mode? With just a normal pool everything is okay, however I get a message saying md5 is not supported in master/slave

Hi ! Had the same issue: for each pgpool server's IP adress you need to set Authentication method to trust in pool_hba.conf if you want pgpool to work in master/slave mode. cheers michael On Thu, Aug 28, 2008 at 10:27 AM, Glyn Astill [EMAIL PROTECTED]wrote: Is there a way to make it throw

Supporting md5 auth with pgpool is fundamentally impossible. 1) PostgreSQL send 32bit encryption salt to pgpool 2) pgpool forwards it to client 3) client encrypt password using the salt 4) pgpool forward the encrypted password to PostgreSQL Problem is, the salt in #1 is a random number and

How does pgpool handle distribution of queries when the slaves are lagging, even if only slightly? Nothing. It's user's responsibility to manage the lagging when using Slony-I like async replications. If you don't like async replications, you could always use pgpool's replication

Sorry for the poor documentations. Actually the settings for using master/slave mode is surprisingly simple. If you are running Slony master on host foo port 5432 and a slave on host bar port 5433, the settings for pgpool.conf would look something like: backend_hostname0 = 'foo'

master_backend_hostname is a directive name for pgpool(I). I strongly recommend to use pgpool-II. Hi Tatsuo, I can see now that I clicked the link to download pgpoolII then downloaded pgpoolI by mistake. Thanks for all the help. Glyn Send instant messages to your online friends
