pg_class has a relnamespace column. You can create and access tables in schemas other than the system namespace; however, there's no search path yet, and not all operations work yet on tables outside the system namespace.

Create a new GUC variable search_path to control the namespace search path. The default behavior if no per-user schemas are created is that all users share a 'public' namespace, thus providing behavior backwards compatible with 7.2 and earlier releases. Probably the semantics and default setting will need to be fine-tuned, but this is a start.

Further cleanups for relations in schemas: teach nextval and other sequence functions how to cope with qualified names. Same code is also used for int4notin, currtid_byrelname, pgstattuple. Also, move TOAST tables into special pg_toast namespace.

extern Oid TypenameGetTypid(const char *typname);
pg_type has a typnamespace column; system now supports creating types in different namespaces. Also, cleanup work on relation namespace support: drop, alter, rename commands work for tables in non-default namespaces.

Reimplement temp tables using schemas. The temp table map is history; temp table entries in pg_class have the names the user would expect.
