Hmph ... works for me. Where by "works", I mean "the dump contains
constraints and indexes belonging to tables in the specified schema,
and not any others". Maybe you could provide a little more detail?

(One thing I notice is that the dump doesn't contain a "CREATE
SCHEMA schema" command, so you have to do that manually before
you restore. I guess this fits with the definition of the switch
as selecting objects *in* the named schema, but it's still a
possible gotcha.)

What version? As I see:

pg_dump -U postgres -d production -n utility -f utility_sch.sql

In utility_sch.sql:

CREATE SCHEMA utility;

I ask because the docs:

https://www.postgresql.org/docs/12/app-pgdump.html

"Dump only schemas matching pattern; this selects both the schema
itself, and all its contained objects. "

support the idea that the schema definition is dumped.

Caffeine kicked in, now I remember how the above happens:

pg_restore -n utility -f pgrestore_utility.sql /production_12.out

In pgrestore_utility.sql there is no CREATE SCHEMA.

This came up in a previous thread:

Still not clear what was not working in the first place?
