Temporarily modifies the table locking logic to use a standard `LOCK TABLE ... IN ACCESS SHARE MODE` command when running against Cloudberry. This change is necessary because Cloudberry, which is based on PostgreSQL 14, does not support the `COORDINATOR ONLY` clause that was introduced in GPDB 7 as a performance optimization. The use of this unsupported syntax was causing `gpbackup` to panic during the initial table locking phase. A TODO comment has been added to both modified functions (`LockTables` and `LockTableNoWait`) to indicate that this is a workaround. The logic should be reverted to use the `COORDINATOR ONLY` optimization once Cloudberry implements this feature for feature and performance parity with GPDB 7.
