Wanted to get a preliminary look at this PR while some open questions around cross database type references are resolved. The work done here is maybe another reason why it would be easier to do more of dump on the server side. |

For cross-version compatibility, be careful to tolerate dump talking to a server prior to your changes being available.

(I have commented elsewhere, including on #28948, that the current architecture is flawed - all this logic should be done server-side, in which case the cross-version compat story is much easier.)

Thanks for updating the PR but this is a bit out of my depth for a quality review right now.
As you hand the review over to another engineer, be mindful to check:
- that this code works fine when ran with a server running at a lower version
- that the tests exercise the various error cases

@dt can you take a look at this PR. Maybe @jordanlewis could take a look at the enum specific things. |

overall LGTM though like @knz I'd prefer to move some of the more involved enum rendering logic to crdb_internal.create_statements

this should be fine -- it is emitting a setting that is only known to 20.2+ it isn't sending it to the server. the types are only understood by a new server so it is fine if the setting is too.

heh, yeah I felt that I was taking it a step too far here. I'll extend the internal table I'm referencing to return the necessary information.
yeah, i'd also have preference for the crdb_internal.create_statements table doing more of this for us than baking a lot of logic into the client.

I'm not sure what else I can push to the server. Unfortunately, the driver doesn't return arrays as []string, but rather as []byte that needs to be decoded into an array.
