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?
