AIX & PostgreSQL - Say wha?

So I am currently supporting and administering a real mixed bag of installations.

The current versions of PostgreSQL I'm supporting are from 7.4 up to 8.4 in production, with two 9.0 databases on their way through potential upgrade (and hopefully many more should I get my own way).

The operating systems I have to contend with include RHEL 4, 5 and 6, AIX 5.3 on PowerPC and even Centos, all of these in a mix of 32 & 64 bit installations. I'm pretty sure I've even seen a Debian installation lying around somewhere...

So why is AIX a problem? Well, it's not; technically speaking of course. The only real annoyance is the endianness. It's well documented in the PostgreSQL installation platform notes that AIX is, shall we say, Quirky? Basically, AIX makes PostgreSQL a real pain to compile and install. This wasn't something that I had to do, but I did inherit it, and as such, any thoughts of upgrading PostgreSQL on AIX seem to turn me to nightmares. I just don't fancy hours of battling with compiler errors. Not that I'm not used to compiler errors you understand; having been a C/C++ in a previous incarnation they make (some) sense to me. I did, however, leave that profession, and as such was hoping to not have to worry about endianness and it's resulting problems at any point in this role.

Alas, I fear I'm going to have to dig in and get on with it! The question is; how soon?
