See pg_catalog.pg_namespace or information_schema.schemata.
A SQL "schema" object is often called a "namespace".
BTW, a subject line which is related to the question is a good idea
-- you might have used "What system table or view for schemas?" or
similar. Given the volume of posts to these lists, many people
scan the list of subject lines and pick only some to read.
