Hi,
I found that by default WAL_DEBUG macro has been defined in
9.2dev and 9.1. I'm very surprised at this. Why does WAL_DEBUG
need to be defined by default? The performance overhead
introduced by WAL_DEBUG is really vanishingly low?
WAL_DEBUG was defined in the following commit:
53dbc27c62d8e1b6c5253feba04a5094cb8fe046
----------------------
Support unlogged tables.
The contents of an unlogged table are WAL-logged; thus, they are not
available on standby servers and are truncated whenever the database
system enters recovery. Indexes on unlogged tables are also unlogged.
Unlogged GiST indexes are not currently supported.
