 1. You want run `onedump` in Kubernetes, ECS, or any other container environment.
 
 2. Currently, `onedump` does not provide a native PostgreSQL dumper out of the box. Therefore, for PostgreSQL, you need to have `pg_dump` installed on the same machine. The Docker image includes `pg_dump`, making it easier to run `onedump` without additional manual installation.

 #### Use a specific pg_dump version
-The docker image contains mysql client, postgresql15-client and postgresql16-client. By default it uses postgresql16-client. However, you can pass an environemnt `PG_VERSION` to swtich postgresql client version between `15` and `16`. For example, `docker run -e PG_VERSION=15 julianli/onedump:v1.2.0-arm64 -f config.yaml`.

 ## Prerequisites
 
 `onedump` provides a native MySQL dumper, allowing you to use the `onedump` binary to dump your MySQL database contents without needing `mysqldump` be installed on your machine.
 
-If you need more advanced MySQL dump features or for PostgreSQL dump, you may want to use `mysqldump` or `pg_dump` dumper, which you need to install the below dependencies.
