"No space left on device" in ci test.


Hi all,
I'm encountering a persistent issue in CI while working on the UDP2 Interconnect PR (https://github.com/apache/cloudberry/pull/1357). Specifically, the `ic-good-opt-on` workflow frequently fails with a “No space left on device” error during the cbdb_parallel test.
Here is an example of the failure:
```
ERROR: could not write to file "pg_wal/xlogtemp.*": No space left on device
ERROR: current transaction is aborted, commands ignored until end of transaction block
```
The failure consistently happens at the following step in cbdb_parallel:
```
insert into t1 select i, i from generate_series(1, 10000000) i;
```
This test inserts 10 million rows and seems to trigger heavy WAL generation. Any suggestions or guidance would be greatly appreciated.
Thanks in advance for your help!
