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.
