[ADMIN] Confuse about the behaveior of PreparedStatement.executeBatch (jdbc)
Hi, I have a DB writer program written in Java, it do batch updates, and will try to update each record in a batch if it failed. I think no any record in a batch will be update if the batch failed, but weirdly I found a few records update twice(very little amount among all records). Well, there is less stuff about postgresql jdbc driver. I wanna know if executeBatch really keep all the records in a batch untouched when the batch failed. Any help is appreciate. -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
[ADMIN] pooler/router?
Hi all, I have a customer who needs to split a set of pg databases that have outgrown any possible big iron and needs to do it quick, at zero impact on lots of existing and basically undocumented applications. I was wondering whether there is anything I can drop in as a middleware, that will get any incoming connections to oldserver:5432 and reroute them to a set of individual boxes, based on the targeted database. PgPooler + routing, sort of. Any hint is greatly appreciated.

You might want to mention what autoCommit is set to during the attempt. -Kevin -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
[ADMIN] allow a user to see current_query in pg_stat_activity in 8.4
This seems like a question whose answer must be right in front of me, but I am not seeing it. We want to create a role used by a monitor to check for IDLE in Transaction with the most restrictive permissions we can on a 8.4.13 instance. The user has been granted connect privilege to the database and some limited permissions to user tabhles that need to be monitored. But pg_stat_activity shows only insufficient privilege I've trolled the archives and postgres docs with no success. Could some kind soul point me in the right direction ? Thanks! Greg Williamson

You can only see the query of another session if (1) you are a superuser, or (2) you are the same user the other session is logged in as. Table permissions have nothing to do with this. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin

Thanks for the swi8ft answer even if wasn't the one I was hoping for. ;-} Another solution suggests itself then ... thanks!
