Hello! There is a good chance that I'll be trying to deploy PostgreSQL on some older IBM Power5+ machines (running AIX 5.2 or 5.3). I wonder if any of you coukl give me some hints on using PostgreSQL on that platform? Installation Looks like I'll be compiling from source (or are there any good packages available?). It also seems to be a good idea to use xlc instead of gcc (according to the FAQ). Tuning Are there any tuning hints at operating system level that I should pay more attention to? I.e. jfs/jfs2 mount options, sync settings, etc. etc.? Anyway, what are your feelings with regard to using PostgreSQL under AIX? How do you feel it compares to other "big" Unixen as far as PostgreSQL goes? Regards, Dawid
