   # Proposed changes
   
   Issue Number: N/A
   
   ## Problem Summary:
   
   The Postgres CDC database sync only accepts `initial` and `latest-offset` 
for `scan.startup.mode`, so any other value silently falls back to `initial`. 
Flink CDC's `StartupOptions.committed()` (start from the slot's last committed 
position) was unreachable.
   
   This PR adds `committed-offset` as a startup mode value for 
`PostgresDatabaseSync` and maps it to `StartupOptions.committed()`.
   
   Supersedes #630 (rebased on the current module layout).
   
   ## Checklist(Required)
   
   1. Does it affect the original behavior: No
   2. Has unit tests been added: No Need
   3. Has document been added or modified: No Need
   4. Does it need to update dependencies: No
   5. Are there any changes that cannot be rolled back: No
   
   ## Further comments
   
   Compiles with `mvn install -DskipTests -Pflink1 -pl 
flink-doris-connector-flink1 -am`. `StartupOptions.committed()` exists in 
flink-cdc 3.5.0.
