Concurrent testing PostgreSQL Vs MySQL

Hi All,

I tested "concurrent testing" in MySQL. It works fine. But I couldn't do in PostgreSQL 7.3.4 on HPUX IPF. I got deadlock problem. I used the PHP script to update table( one script increment the column & another one decrement the column). Is the postgres support the concurrent access to update database?

I got the following errors:

test=# ERROR: deadlock detected
ERROR: deadlock detected
ERROR: deadlock detected
....

Regs,
Durai.
