Обсуждение: Console Output

Hi, I am starting to mess around with PostgreSQL source code and wanted to print some information to console in relation to pages.  I see that the buffer manager (specifically in bufmgr.c) is the best place to access this information and I believe I know where I would like to place my code.  Is there an easy way to just print this information to a console?  I am pretty new at this type of modification so any help would be greatly appreciated

elog(LOG, ...) is a pretty common way of pushing quick-hack debug output
to the postmaster log.  Depending on how you've got the postmaster's log
output configured, plain old fprintf(stderr, ...) might work as well for
slightly less overhead.
