Re: Support logical replication of DDLs

Hello

I think this is a pretty interesting and useful feature.

Did you see some old code I wrote towards this goal?
https://www.postgresql.org/message-id/20150215044814.GL3391@alvh.no-ip.org
The intention was that DDL would produce some JSON blob that accurately
describes the DDL that was run; the caller can acquire that and use it
to produce working DDL that doesn't depend on runtime conditions.  There
was lots of discussion on doing things this way.  It was ultimately
abandoned, but I think it's valuable.
