Stephen Frost e45319bb77 For 8.0 servers, get last built-in oid from pg_database 
We didn't start ensuring that all built-in objects had OIDs less than
16384 until 8.1, so for 8.0 servers we still need to query the value out
of pg_database.  We need this, in particular, to distinguish which casts
were built-in and which were user-defined.

For HEAD, we only worry about going back to 8.0, for the back-branches,
we also ensure that 7.0-7.4 work.

* pg_dump.c
* pg_dump is a utility for dumping out a postgres database
* into a script file.
*
* Portions Copyright (c) 1996-2016, PostgreSQL Global Development Group
* Portions Copyright (c) 1994, Regents of the University of California
*
* pg_dump will read the system catalogs in a database and dump out a
* script that reproduces the schema in terms of SQL that is understood
* by PostgreSQL
*
* Note that pg_dump runs in a transaction-snapshot mode transaction,
* so it sees a consistent snapshot of the database including system
* catalogs. However, it relies in part on various specialized backend
* functions like pg_get_indexdef(), and those things tend to look at
* the currently committed state. So it is possible to get 'cache
* lookup failed' error if someone performs DDL changes while a dump is
* happening. The window for this sort of thing is from the acquisition
* of the transaction snapshot to getSchemaData() (when pg_dump acquires
* AccessShareLock on every table it intends to dump). It isn't very large,
* but it can happen.

* THROTTLE:
*
* There was considerable discussion in late July, 2000 regarding
* slowing down pg_dump when backing up large tables. Users with both
* slow & fast (multi-processor) machines experienced performance
* degradation when doing a backup.
*
* Initial attempts based on sleeping for a number of ms for each ms
* of work were deemed too complex, then a simple 'sleep in each loop'
* implementation was suggested. The latter failed because the loop
* was too tight. Finally, the following was implemented:
*
* If throttle is non-zero, then
* See how long since the last sleep.
* Work out how long to sleep (based on ratio).
* If sleep is more than 100ms, then
* sleep
* reset timer
* EndIf
* EndIf
*
* where the throttle value was the number of ms to sleep per ms of
* work. The calculation was done in each loop.
*
* Most of the hard work is done in the backend, and this solution
* still did not work particularly well: on slow machines, the ratio
* was 50:1, and on medium paced machines, 1:1, and on fast
* multi-processor machines, it had little or no effect, for reasons
* that were unclear.
*
* Further discussion ensued, and the proposal was dropped.
*
* For those people who want this feature, it can be implemented using
* gettimeofday in each loop, calculating the time since last sleep,
* multiplying that by the sleep ratio, then if the result is more
* than a preset 'minimum sleep time' (say 100ms), call the 'select'
* function to sleep for a subsecond period ie.
*
* select(0, NULL, NULL, NULL, &tvi);
*
* This will return after the interval specified in the structure tvi.
* Finally, call gettimeofday again to save the 'last sleep time'.

* BuildArchiveDependencies - create dependency data for archive TOC entries
*
* The raw dependency data obtained by getDependencies() is not terribly
* useful in an archive dump, because in many cases there are dependency
* chains linking through objects that don't appear explicitly in the dump.
* For example, a view will depend on its _RETURN rule while the _RETURN rule
* will depend on other objects --- but the rule will not appear as a separate
* object in the dump. We need to adjust the view's dependencies to include
* whatever the rule depends on that is included in the dump.
*
* Just to make things more complicated, there are also "special" dependencies
* such as the dependency of a TABLE DATA item on its TABLE, which we must
* not rearrange because pg_restore knows that TABLE DATA only depends on
* its table. In these cases we must leave the dependencies strictly as-is
* even if they refer to not-to-be-dumped objects.
*
* To handle this, the convention is that "special" dependencies are created
* during ArchiveEntry calls, and an archive TOC item that has any such
* entries will not be touched here. Otherwise, we recursively search the
* DumpableObject data structures to build the correct dependencies for each
* archive TOC item.
