Out of shared memory in postgres 8.4.2 and locks

Hi All,

 

We have installed postgres 8.4.2 on production.

 

We have a parition table structure for one of the table. 

 

when i am drop the master table we get the following error.

 

drop table table_name cascade;
WARNING:  out of shared memory
ERROR:  out of shared memory
HINT:  You might need to increase max_locks_per_transaction.

 

FYI : This sql was working fine on Postgres 8.3

 

Can some one please let me know what is going wrong here.

 

Regards

Vidhya
