Postgres 8.3.10 Alter Table Waiting issue

Hi Team,

I am trying to add column to the table that's hanging.

alter table hr_firms add column_name biginit;

This is the lock I see in the db

relation | 564709 | 586888 | | | |
| | | | 1/8 | 1871 |
AccessExclusiveLock | f

Version of postgres: 8.3.10

Is it known issue or any fix available?
