Hi,
Does anyone know how to enable WAL_DEBUG?
I download postgresql 9.2.3 src code and compile it as follow:
modify ./src/include/pg_config_manual.h
/*
* Enable debugging print statements for WAL-related operations; see
* also the wal_debug GUC var.
*/
#define WAL_DEBUG 4
./configure --without-readline --without-zlib CPPFLAGS='-DWAL_DEBUG'
I don't see anything special log to the log file.
I even try to add a line wal_debug=number to the postgresql.conf, doesn't help either.
Thanks~
Ning
