Hi,
We are using postgresql 7.3.2 on lunux platform. We performed locking test as follows via JDBC:
Started 2 concurrent transaction with autocommit false and isolation READ_COMMITTED :
Transaction 1:
===========
Update row 1
Sleep for 30 seconds
commit:
Transaction 2:
===========
Updated row 10000
commit
The second update had to wait for the first update operation to finish. We also made sure that the 2 unrelated rows are not on the same page.
Is this expected behavior ?
Does update lock the whole table ?
Regards,
Ravi
