Hi guys,
I'm using PostgreSQL 9.2 in two different servers.
server1 (Master Postgres DB server, running Postgres 9.2 / 128GB
ram) -
RAID 10 Magnetic disks
server2 (Master Postgres DB server, running Postgres 9.2 / 128GB
ram) -
EBS (AWS) io2 10k IOPS
When I run a query, I get this error:
ERROR: canceling statement due to statement timeout
statement_timeout is 0 in both servers.
However, on server1 I am able to run the query. Only on server2
that I
get that error.
Why? If it is same DB???
It is not the same DB if it is on two different servers not
connected by replication. More to the point statement_timeout is a
client connection setting, so is the client you use to connect to
server2 the same as the one you use for server1?
Is AWS being 'helpful' and setting a timeout?
Is there anything in the log before the ERROR shown above that
indicates something is setting statement_timeout?

Same database, different database servers; server1 is the old Master
server and I'm using it to compare.
It is not the client, because if I run the query manually using explain
analyze i get the error:
Well that is a client also.
Are you sure there is not something in your AWS setup that is doing this?
live_db=> explain analyze
SELECT DISTINCT id0
FROM
(SELECT
[...]
ERROR: canceling statement due to statement timeout
just a remind that on server1 works, but on server2 it doesn't.
Server1 is not on AWS and server2 is, see above.
