3 * pg_dump.c
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.
24 *

2444 * THROTTLE:
2445 *
2446 * There was considerable discussion in late July, 2000 regarding
2447 * slowing down pg_dump when backing up large tables. Users with both
2448 * slow & fast (multi-processor) machines experienced performance
2449 * degradation when doing a backup.
2450 *
2451 * Initial attempts based on sleeping for a number of ms for each ms
2452 * of work were deemed too complex, then a simple 'sleep in each loop'
2453 * implementation was suggested. The latter failed because the loop
2454 * was too tight. Finally, the following was implemented:
2455 *
2456 * If throttle is non-zero, then
2457 * See how long since the last sleep.
2458 * Work out how long to sleep (based on ratio).
2459 * If sleep is more than 100ms, then
2460 * sleep
2461 * reset timer
2462 * EndIf
2463 * EndIf
2464 *
2465 * where the throttle value was the number of ms to sleep per ms of
2466 * work. The calculation was done in each loop.
2467 *
2468 * Most of the hard work is done in the backend, and this solution
2469 * still did not work particularly well: on slow machines, the ratio
2470 * was 50:1, and on medium paced machines, 1:1, and on fast
2471 * multi-processor machines, it had little or no effect, for reasons
2472 * that were unclear.
2473 *
2474 * Further discussion ensued, and the proposal was dropped.
2475 *
2476 * For those people who want this feature, it can be implemented using
2477 * gettimeofday in each loop, calculating the time since last sleep,
2478 * multiplying that by the sleep ratio, then if the result is more
2479 * than a preset 'minimum sleep time' (say 100ms), call the 'select'
2480 * function to sleep for a subsecond period ie.
2481 *
2482 * select(0, NULL, NULL, NULL, &tvi);
2483 *
2484 * This will return after the interval specified in the structure tvi.
2485 * Finally, call gettimeofday again to save the 'last sleep time'.

9942 * 1) the column has no not-null constraints. In that case, ->notnull_constrs
9943 * (the constraint name) remains NULL.
9944 * 2) The column has a constraint with no name (this is the case when
9945 * constraints come from pre-18 servers). In this case, ->notnull_constrs
9946 * is set to the empty string; dumpTableSchema will print just "NOT NULL".
9947 * 3) The column has an invalid not-null constraint. This must be treated
9948 * as a separate object (because it must be created after the table data
9949 * is loaded). So we add its OID to invalidnotnulloids for processing
9950 * elsewhere and do nothing further with it here. We distinguish this
9951 * case because the "notnull_invalidoid" column has been set to a non-NULL
9952 * value, which is the constraint OID. Valid constraints have a null OID.
9953 * 4) The column has a constraint with a known name; in that case
9954 * notnull_constrs carries that name and dumpTableSchema will print
9955 * "CONSTRAINT the_name NOT NULL". However, if the name is the default
9956 * (table_column_not_null) and there's no comment on the constraint,
9957 * there's no need to print that name in the dump, so notnull_constrs
9958 * is set to the empty string and it behaves as case 2.
9959 *
9960 * In a child table that inherits from a parent already containing NOT NULL
9961 * constraints and the columns in the child don't have their own NOT NULL
9962 * declarations, we suppress printing constraints in the child: the
9963 * constraints are acquired at the point where the child is attached to the
9964 * parent. This is tracked in ->notnull_islocal; for servers pre-18 this is
9965 * set not here but in flagInhAttrs. That flag is also used when the
9966 * constraint was validated in a child but all its parent have it as NOT
9967 * VALID.
9968 *
9969 * Any of these constraints might have the NO INHERIT bit. If so we set
9970 * ->notnull_noinh and NO INHERIT will be printed by dumpTableSchema.
9971 *
9972 * In case 4 above, the name comparison is a bit of a hack; it actually fails
9973 * to do the right thing in all but the trivial case. However, the downside
9974 * of getting it wrong is simply that the name is printed rather than
9975 * suppressed, so it's not a big deal.
9976 *
9977 * invalidnotnulloids is expected to be given as NULL; if any invalid not-null
9978 * constraints are found, it is initialized and filled with the array of
9979 * OIDs of such constraints, for later processing.
