Bruce Momjian	0a78320057	pgindent run for 9.4 ... This includes removing tabs after periods in C comments, which was applied to back branches, so this change should not effect backpatching.	12 years ago
Tom Lane	ea177a3ba7	Remove unportable use of anonymous unions from reorderbuffer.h. ... In b89e151054 I had assumed it was ok to use anonymous unions as struct members, but while a longstanding extension in many compilers, it's only been standardized in C11. To fix, remove one of the anonymous unions which tried to hide some implementation specific enum values and give the other a name. The latter unfortunately requires changes in output plugins, but since the feature has only been added a few days ago... Andres Freund	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.
