With the freshly retrieved current source, now PostgreSQL is running
fine on an AIX 5L box. Thanks Tom.
BTW, I have done some benchmarking using pgbench on this machine and
found that 7.2 is almost two times slower than 7.1. The hardware is a
4way machine. Since I thought that 7.2 improves the performance for
SMP machines, I'm now wondering why 7.2 is so slow.
postgresql.conf paramters changed from default values are:
max_connections = 1024
wal_sync_method = fdatasync
shared_buffers = 4096
deadlock_timeout = 1000000
configure option is: --enable-multibyte=EUC_JP
Of cousre, these setting are identical for both 7.1 and 7.2.
See attached graph...
