 * The data structures used to store system catalog information.  Every
 * dumpable object is a subclass of DumpableObject.
 *
 * NOTE: the structures described here live for the entire pg_dump run;
 * and in most cases we make a struct for every object we can find in the
 * catalogs, not only those we are actually going to dump.  Hence, it's
 * best to store a minimal amount of per-object info in these structs,
 * and retrieve additional per-object info when and if we dump a specific
 * object.  In particular, try to avoid retrieving expensive-to-compute
 * information until it's known to be needed.  We do, however, have to
 * store enough info to determine whether an object should be dumped and
 * what order to dump in.

 * locking a table for that either (that can happen if we are going
 * to dump "ALL" components for a table).
 *
 * We DO need locks for DEFINITION, due to various server-side
