Subject: [PATCH] Dockerfile update to install specific version of pg client
 tools

Running the existing image against a postgres 15 database results in

```
pg_dump: error: server version: 15.8 (Debian 15.8-1.pgdg120+1); pg_dump version: 14.0 (Debian 14.0-1.pgdg100+1)
pg_dump: error: aborting because of server version mismatch
```

This update to the Dockerfile allows using a build arg to specify the version of postgres you want to install. You could use this to build one for each version of postgres.

According to https://wiki.postgresql.org/wiki/Apt, the versions currently available in the apt repo are 10, 11, 12, 13, 14, 15, 16, 17, 18 devel
