Andres Freund	eef34e5236	test_decoding: Protect against rare spurious test failures. ... A bunch of tests missed specifying that empty transactions shouldn't be displayed. That causes problems when e.g. autovacuum runs in an unfortunate moment. The tests in question only run for a very short time, making this quite unlikely.

Andres Freund	0ef3c29a4b	Improve documentation about binary/textual output mode for output plugins. ... Also improve related error message as it contributed to the confusion.

Robert Haas	97e899e1b8	Fix test_decoding regression test outputs. ... Commit 6f37c08057 removed whitespace from the SQL file but not the expected-output file, and commit 7e8db2dc42 changed the error message without updating the expected outputs.	12 years ago
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.
