setting connection/ query timeout
Hi All
I am using postgres-8.1.2 . In postgresql.conf I have set :
#statement_timeout = 0
I am executing the below query just to check if postgres is allowing connections or not .
psql -Uslon -d<db_name> -h <IP> -c "select 1;"
Sometimes this query gets stuck for unknown reason . So, for this particular query I want to set a timeout
. I dont want to change "statement_timeout" in postgresql.conf as this would affect all the connections/queries.
I just want to set timeout for above mentioned query . How can I do that ??
Moreover, Just in case there is some problem while getting connection to postgres while executing the above query ,
I want the query to exit . How can I set connection timeout for that ??
Thanks..

You can set a timeout only valid for the session using SET:
=> set statement_timeout to 1000;
SET
=> select pg_sleep(2);
