E. System Information Functions

    Add functions for error-free pg_class, pg_proc, pg_type, and pg_operator 
lookups (Yugo Nagata, Nozomi Anzai, Robert Haas)

    For example, to_regclass() does error-free lookups of pg_class, and returns 
NULL for lookup failures.

Probably "error-free" is too strong wording because these functions
are not actualy error free.

test=# select to_regclass('a.b.c.d');
ERROR:  improper relation name (too many dotted names): a.b.c.d
STATEMENT:  select to_regclass('a.b.c.d');
