4 : * pg_dump is a utility for dumping out a postgres database
5 : * into a script file.

9 : *
10 : * pg_dump will read the system catalogs in a database and dump out a
11 : * script that reproduces the schema in terms of SQL that is understood
12 : * by PostgreSQL
13 : *
14 : * Note that pg_dump runs in a transaction-snapshot mode transaction,
15 : * so it sees a consistent snapshot of the database including system
16 : * catalogs. However, it relies in part on various specialized backend
17 : * functions like pg_get_indexdef(), and those things tend to look at
18 : * the currently committed state. So it is possible to get 'cache
19 : * lookup failed' error if someone performs DDL changes while a dump is
20 : * happening. The window for this sort of thing is from the acquisition
21 : * of the transaction snapshot to getSchemaData() (when pg_dump acquires
22 : * AccessShareLock on every table it intends to dump). It isn't very large,
23 : * but it can happen.

2370 : * THROTTLE:
2371 : *
2372 : * There was considerable discussion in late July, 2000 regarding
2373 : * slowing down pg_dump when backing up large tables. Users with both
2374 : * slow & fast (multi-processor) machines experienced performance
2375 : * degradation when doing a backup.
2376 : *
2377 : * Initial attempts based on sleeping for a number of ms for each ms
2378 : * of work were deemed too complex, then a simple 'sleep in each loop'
2379 : * implementation was suggested. The latter failed because the loop
2380 : * was too tight. Finally, the following was implemented:
2381 : *
2382 : * If throttle is non-zero, then
2383 : * See how long since the last sleep.
2384 : * Work out how long to sleep (based on ratio).
2385 : * If sleep is more than 100ms, then
2386 : * sleep
2387 : * reset timer
2388 : * EndIf
2389 : * EndIf
2390 : *
2391 : * where the throttle value was the number of ms to sleep per ms of
2392 : * work. The calculation was done in each loop.
2393 : *
2394 : * Most of the hard work is done in the backend, and this solution
2395 : * still did not work particularly well: on slow machines, the ratio
2396 : * was 50:1, and on medium paced machines, 1:1, and on fast
2397 : * multi-processor machines, it had little or no effect, for reasons
2398 : * that were unclear.
2399 : *
2400 : * Further discussion ensued, and the proposal was dropped.
2401 : *
2402 : * For those people who want this feature, it can be implemented using
2403 : * gettimeofday in each loop, calculating the time since last sleep,
2404 : * multiplying that by the sleep ratio, then if the result is more
2405 : * than a preset 'minimum sleep time' (say 100ms), call the 'select'
2406 : * function to sleep for a subsecond period ie.
2407 : *
2408 : * select(0, NULL, NULL, NULL, &tvi);
2409 : *
2410 : * This will return after the interval specified in the structure tvi.
2411 : * Finally, call gettimeofday again to save the 'last sleep time'.

9686 : *
9687 : * Result row 'r' is for tbinfo's attribute 'j'.
9688 : *
9689 : * There are four possibilities:
9690 : * 1) the column has no not-null constraints. In that case, ->notnull_constrs
9691 : * (the constraint name) remains NULL.
9692 : * 2) The column has a constraint with no name (this is the case when
9693 : * constraints come from pre-18 servers). In this case, ->notnull_constrs
9694 : * is set to the empty string; dumpTableSchema will print just "NOT NULL".
9695 : * 3) The column has an invalid not-null constraint. This must be treated
9696 : * as a separate object (because it must be created after the table data
9697 : * is loaded). So we add its OID to invalidnotnulloids for processing
9698 : * elsewhere and do nothing further with it here. We distinguish this
9699 : * case because the "notnull_invalidoid" column has been set to a non-NULL
9700 : * value, which is the constraint OID. Valid constraints have a null OID.
9701 : * 4) The column has a constraint with a known name; in that case
9702 : * notnull_constrs carries that name and dumpTableSchema will print
9703 : * "CONSTRAINT the_name NOT NULL". However, if the name is the default
9704 : * (table_column_not_null), there's no need to print that name in the dump,
9705 : * so notnull_constrs is set to the empty string and it behaves as case 2.
9706 : *
9707 : * In a child table that inherits from a parent already containing NOT NULL
9708 : * constraints and the columns in the child don't have their own NOT NULL
9709 : * declarations, we suppress printing constraints in the child: the
9710 : * constraints are acquired at the point where the child is attached to the
9711 : * parent. This is tracked in ->notnull_islocal (which is set in flagInhAttrs
9712 : * for servers pre-18).
9713 : *
9714 : * Any of these constraints might have the NO INHERIT bit. If so we set
9715 : * ->notnull_noinh and NO INHERIT will be printed by dumpTableSchema.
9716 : *
9717 : * In case 4 above, the name comparison is a bit of a hack; it actually fails
9718 : * to do the right thing in all but the trivial case. However, the downside
9719 : * of getting it wrong is simply that the name is printed rather than
9720 : * suppressed, so it's not a big deal.
