If you need to get a GNU package, you can find it at your local GNU

mirror site (see http://www.gnu.org/order/ftp.html for a list) or at

keys), then use the "-o" option when running pg_dumpall.

To make the backup, you can use the pg_dumpall command from the
170

version you are currently running. For best results, however, try

to use the pg_dumpall command from PostgreSQL 8.4beta2, since this

If you are going to build for several platforms within the same source

challenging. Both AIX version 4.3 and 5.3 are supported in theory. You

can use GCC or the native IBM compiler xlc. In general, using recent
1019
versions of AIX and PostgreSQL helps. Check the build farm for up to

AIX 5.3 has a problem where sockaddr_storage is not defined to be large

enough. In version 5.3, IBM increased the size of sockaddr_un, the
1063
1071
address structure for Unix-domain sockets, but did not correspondingly
1064
increase the size of sockadr_storage. The result of this is that
1072
increase the size of sockaddr_storage. The result of this is that
1065
1073
attempts to use Unix-domain sockets with PostgreSQL lead to libpq
1066
1074
overflowing the data structure. TCP/IP connections work OK, but not

Unix-domain sockets, which prevents the regression tests from working.

The problem was reported to IBM, and is recorded as bug report

include this fix. Use the command oslevel -r to determine what
1072
maintenance level you are at. An immediate resolution is to alter
1073
_SS_MAXSIZE to = 1025 in "/usr/include/sys/socket.h".

PostgreSQL once you have the corrected header file.

Internet address issues
1086
PostgreSQL relies on the system's getaddrinfo function to parse IP
1087
addresses in listen_addresses, "pg_hba.conf", etc. Older versions of
1088
AIX have assorted bugs in this function. If you have problems related
1089
to these settings, updating to the appropriate fix level shown in Table
1090
1 in the Section called AIX should take care of it.
1094
When implementing PostgreSQL version 8.1 on AIX 5.3, we periodically
1095
ran into problems where the statistics collector would "mysteriously"
1096
not come up successfully. This appears to be the result of unexpected
1097
behaviour in the IPv6 implementation. It looks like PostgreSQL and IPv6
1098
do not play very well together at this time on AIX.
1100
Any of the following actions "fix" the problem.
1102
* Delete the IPv6 address for localhost:
1104
# ifconfig lo0 inet6 ::1/0 delete
1105
* Remove IPv6 from net services. The file "/etc/netsvc.conf" on AIX
1106
is roughly equivalent to "/etc/nsswitch.conf" on Solaris/Linux. The
1107
default, on AIX, is thus:
1111
to deactivate searching for IPv6 addresses.
