That outputs NULL, as well for other tested indexes. Additionally, the
following two lines only apply to the index associtaed with the
primary key, not the table itself, don't they?
> CONSTRAINT pk_clt_rec PRIMARY KEY (id)
> WITH (FILLFACTOR = 10),
I've checked pgModeler and it seems to set such low fill factors
automatically on old primary keys only. Will remove those.

Am I allowed or is it necessary to use LIKE? The docs don't use that
and the description sounds wrong as well.

The option you mention is INCLUDING IDENTITY and that would need to be
AVOIDED to NOT get multiple SEQUENCES?
Mit freundlichen Grüßen,
