"A schema is essentially a namespace: it contains named objects (tables, data
types, functions, and operators) whose names can duplicate those of other
objects existing in other schemas. Named objects are accessed either
by "qualifying" their names with the schema name as a prefix, or by setting a
search path that includes the desired schema(s). A CREATE command specifying an
unqualified object name creates the object in the current schema (the one at
the front of the search path, which can be determined with the function
current_schema). "
