Unfortunately, with some compilers (gcc, I'm looking at you) you get considerably fewer warnings with -O0 than with -O1, even if you specify -Wall. The reason seems to be that some of the warnings need information produces by some of the optimization passes. I usually use -O1 for debug builds, these are usually still at least somewhat debuggable with gdb. best regards, Florian Pflug -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
