I added the following line to postgresql.conf file: log_line_prefix='%t %u %d %h %p %i %l %x ' but got error. 2007-11-29 12:40:41 LOG: syntax error in file "D:/Program Files/PostgreSQL/8.2/data/postgresql.conf" line 482, near token "%" I checked and all options are legal. What I'm doing wrong ? Why error message does not show exact information about error ?
