pg_dump – schema not found

I am trying to dump a schema from Postgres 9.4, running on Cents 6.5, but I get an error:

pg_dump: No matching schemas were found

Here is the command I am running:

pg_dump -U postgres -n "OLD-TODELETE-bushes" --verbose site > output_nf

I am a little confused by this as when I run select schema_name from information_schema.schemata, I can see the schema name.

If I run pg_dump for all schemas the OLD-TODELETE-bushes is dumped to file, as expected.

There are no error’s in the Postgres logs.

Anyone have any ideas?
