Method Iter

postgres/parser/sessiondata/search_path.go:134–144

Iter returns an iterator through the search path. We must include the implicit pg_catalog and temporary schema at the beginning of the search path, unless they have been explicitly set later by the user. We also include pg_extension in the path, as this normally be used in place of the public schema

func (s SearchPath) Iter() SearchPathIter {
	implicitPgTempSchema := !s.containsPgTempSchema && s.tempSchemaName != ""
	sp := SearchPathIter{
		paths:                s.paths,
		implicitPgCatalog:    !s.containsPgCatalog,
		implicitPgExtension:  !s.containsPgExtension,
		implicitPgTempSchema: implicitPgTempSchema,
		tempSchemaName:       s.tempSchemaName,
	}
	return sp
}

// IterWithoutImplicitPGSchemas is the same as Iter, but does not include the
// implicit pg_temp and pg_catalog.
