Re: BUG #6186: out of memory while analyze

Hello,

table design http://pastebin.com/RW6vLAVP

And configuration:

ssl =3D false
shared_buffers =3D 900MB                  # min 128kB
work_mem =3D 100MB                                # min 64kB
maintenance_work_mem =3D 524MB            # min 1MB
fsync =3D off                             # turns forced synchronization on=
 or off
synchronous_commit =3D off                # immediate fsync at commit
full_page_writes =3D off                  # recover from partial page writes
effective_cache_size =3D 1GB
default_statistics_target =3D 8000        # range 1-10000


Also tried change maintenance_work_mem to 2G and same result.
Imposible to set over 2GB (FATAL:  3145728 is outside the valid range
for parameter "maintenance_work_mem" (1024 .. 2097151))

Problem seems to be in default_statistics_target values from approx
6300. Up to 6300 analyze works but on another machine (64bit) works
10000 without problems on same but larger table (more data)
