Hi Christoph !

This was also my first thought. MySQL has a nice "SHOW CREATE TABLE"
command and it seems to me that putting this code on the server would be
a benefit for any GUI tools that tries to export tables structure and
probably also for schema versionning tools.

https://dev.mysql.com/doc/refman/8.0/en/show-create-table.html

I looked at the pg_dump code and tried to build a C extension that would
include the dumputils.h header file. But pg_dump is a client-side tool,
so parts of this code would have to be moved to the server-side. I don't
have the time and knowledge to propose a patch like that by myself. But
if someone is interested, I can help...

Agreed.

Thanks for your answer
