In this case, it is cleaner to just set the schema name in CreateSchemaStmtContext.schemaname to the role in the RoleSpec if there is no schema set in the query, because the schema name will have the same name as the role. That also makes the handling of each element in schemaElts simpler.
I noticed that in CreateSchemaCommand there is logic that fills schema name with the role name if it is not specified. Do you think we can save the new-filled schema name into CreateSchemaStmt.schemaname there?
The regression tests cruelly lacks of checks here. This is not a pattern of CREATE SCHEMA known a lot, but we should do better.
Agreed. It's better to have a case covering this pattern of CREATE SCHEMA.
