Tom/Matthew,
I also tried the same macro with the xlc compiler with similar results
in that pg_dump now works as expected :-)
For info here's my build setup:-
./configure CC=xlc LIBS="-lssl -lcrypto -lz -lreadline -lcurses -lld
-lmass -lm" CFLAGS="-qlanglvl=extc89 -D_LINUX_SOURCE_COMPAT"
--with-template=aix --prefix=/home/ahastie/pgbuild
--with-includes=/opt/freeware/include
--with-libraries=/opt/freeware/lib
gmake
gmake check
gmake install
Tom: Is this something we should get added into the AIX Platform
specific notes?
Regards,
Andrew

Tom,
Following on from that man page extract I tried a build using the suggested compiler macro (_LINUX_SOURCE_COMPAT) ...
export "CC=/opt/freeware/bin/gcc -maix64"
export OBJECT_MODE=64
export CFLAGS="-D_LINUX_SOURCE_COMPAT -maix64 -g"
export LDFLAGS="-maix64 -Wl,-bbigtoc"
export AR="ar -X64"
export "CC=/opt/freeware/bin/gcc -maix64"
./configure --enable-debug --prefix=/opt/serviceMonitoring/postgres_9.2.1 --disable-thread-safety --enable-cassert
make
cd contrib
make
cd ..
make install
cd contrib
make install
... and tried it out ...
"/opt/serviceMonitoring/postgres_9.2.1/bin/pg_dump" --port 65432 --username "postgres" --verbose --schema-only --binary-upgrade -f dump.out template1
.. and the full dump as per pg_upgrade ...
"/opt/serviceMonitoring/postgres_9.2.1/bin/pg_dumpall" --port 65432 --username "postgres" --schema-only --binary-upgrade -f pg_upgrade_dump_all.sql
.. both of which worked without any problems.
Hope that helps.
Matthew

Oh! Given your previous comment about there not being any user-defined
aggregates, I see what the problem is. AIX must be one of the platforms
where malloc(0) is defined to return NULL rather than a pointer to a
zero-size block. pg_malloc is not coping with that.
A quick fix would be
pg_malloc(size_t size)
{
void *tmp;
tmp = malloc(size);
- if (!tmp)
+ if (!tmp && size)
{
psql_error("out of memory\n");
exit(EXIT_FAILURE);
}
but I'm not sure if that's the best answer overall. Will take it up in
-hackers.
