Well, i'm wrong.
A pgbch (pgbench) transcation limited to :
BEGIN;
END;
Will hang too (with the same gdb stack trace), but i need to increase the
number of client to see it.
But, when the doOne() function is just doing :
for (j = 0; j < 1000000; j++) { }
pgbch never hang.
In that case, except doConnect() the lib ecpg is not used at all by the
threads.
