Hi.

 

 

I am korean database engineer.

 

my english skill is very poor.

 

but i desire that you teach this situation.

 

 

um...

 

I am testing postgresql performance  in these days;

 

today, I found this situation.

 

 

 

Session 1. -

 

begin;

delete from XXXX;

 

 

Session 2 -

 

delete from XXXX;

 

 

thus, it occured row level locking.

 

 

 

 

so. i killed Session 1's PID with kill -9 commands
 

 

killing it with -9 crashed the whole PostgreSQL server, don't do that. Instead just login to the database and run the function pg_cancel_backend() http://www.postgresql.org/docs/8.4/static/functions-admin.html, much more safe way.

regards
