Andres Freund	626bfad6cc	Fix decoding of consecutive MULTI_INSERTs emitted by one heap_multi_insert(). ... Commit 1b86c81d2d fixed the decoding of toasted columns for the rows contained in one xl_heap_multi_insert record. But that's not actually enough, because heap_multi_insert() will actually first toast all passed in rows and then emit several *_multi_insert records; one for each page it fills with tuples. Add a XLOG_HEAP_LAST_MULTI_INSERT flag which is set in xl_heap_multi_insert->flag denoting that this multi_insert record is the last emitted by one heap_multi_insert() call. Then use that flag in decode.c to only set clear_toast_afterwards in the right situation. Expand the number of rows inserted via COPY in the corresponding regression test to make sure that more than one heap page is filled with tuples by one heap_multi_insert() call. Backpatch to 9.4 like the previous commit.	12 years ago
Andres Freund	1b86c81d2d	Fix decoding of MULTI_INSERTs when rows other than the last are toasted. ... When decoding the results of a HEAP2_MULTI_INSERT (currently only generated by COPY FROM) toast columns for all but the last tuple weren't replaced by their actual contents before being handed to the output plugin. The reassembled toast datums where disregarded after every REORDER_BUFFER_CHANGE_(INSERT|UPDATE|DELETE) which is correct for plain inserts, updates, deletes, but not multi inserts - there we generate several REORDER_BUFFER_CHANGE_INSERTs for a single xl_heap_multi_insert record. To solve the problem add a clear_toast_afterwards boolean to ReorderBufferChange's union member that's used by modifications. All row changes but multi_inserts always set that to true, but multi_insert sets it only for the last change generated. Add a regression test covering decoding of multi_inserts - there was none at all before. Backpatch to 9.4 where logical decoding was introduced. Bug found by Petr Jelinek.	12 years ago

Heikki Linnakangas	afd0fcbc5d	Fix test_decoding test case's check that slot has been dropped. ... pg_stat_replication shows connected replication clients. The ddl test case never has any replication clients connected, so querying pg_stat_replication is pointless. To check that a slot has been dropped correctly, query pg_replication_slots instead.

Robert Haas	b89e151054	Introduce logical decoding. ... This feature, building on previous commits, allows the write-ahead log stream to be decoded into a series of logical changes; that is, inserts, updates, and deletes and the transactions which contain them. It is capable of handling decoding even across changes to the schema of the effected tables. The output format is controlled by a so-called "output plugin"; an example is included. To make use of this in a real replication system, the output plugin will need to be modified to produce output in the format appropriate to that system, and to perform filtering. Currently, information can be extracted from the logical decoding system only via SQL; future commits will add the ability to stream changes via walsender.
