Wow, nice catch, nice analysis. Checking now whether my AIX5.2/3 boxes
set this correctly.

Subject: [PORTS] PostgreSQL 8.0.3, AIX 5.1, getaddrinfo, AI_NUMERICHOST
Hello everyone,
I ran into a minor bug with PostgreSQL 8.0.3 compiled with xlc on AIX 5.1 (5100-04). Basically it worked fine
connectingvia unix domain sockets but when you connected to it using TCP/IP with JDBC the child process would SEGV. I
trackedthe problem to a call to getaddrinfo while evaluating the host based access control rules.
The code in function parse_hba on line 752 of hba.c sets the ai_flags member of the addrinfo struct to AI_NUMERICHOST.
Thisis eventually passed into a call to getaddrinfo that results in the SEGV. The manual page from the box implies that
atleast this version of AIX does not the AI_NUMERICHOST flag. (As opposed to, say, Solaris which clearly
does.)
Ifdefing the code so that ai_flags is set to zero on AIX fixes the problem.
Anyway, I hope this is helpful to someone or the right place to send such notes. Please let me know if you need any
additionalinformation.
Thanks,
logan
