As luck would have I've put some thought into this problem before as well. Having reviewed the code quite a bit, and played around with the backend, my intuition tells me that the following would work. Write a custom "cluster-aware" postmaster so it distributes queries to various machines. Of

I think you are right about this. When people look up a timezone, what we see is the offset to UTC. UTC + (offset) should equal current time. We should be consistent. And since the timestamp with timezone is relatively recent, maybe it will not be so painful to change the behaviour of extra

Being new to Postgres, I understand how frustrating tuning is. I've been working on some very basic queries, and trying to get some decent performance. I know the problem isn't with io on the system, since I can use other tests that far exceed the amount of data being written through postgres, so I

This week I have done some performance tuning at a customer's office. We have beaten (demoralized) MS SQL and DB2 in serializable mode and DB2 in any transaction isolation level :). By the way: In case of very simple statements SERIALIZABLE is about 3 times faster than READ COMMITTED. I expecte

Hi, Does anybody know why vacuum full does not relcaim deleted rows if a open transaction which started before the deletion happens is running even on a different database? Here is an example: T1: psql db1 T2: psql db2 T3: psql db2 T2: create table t1(i int); insert into t1 values(1); T1: begin

Chris, would be the right solution to make tsearch V2 to be fully incompatible with old tsearch (so both version could live in one database) and release tsearch v2 in separate directory. This way require some additional work but would not confuse people. As a bonus, people could start playing with
