Re: BUG #6186: out of memory while analyze

Hello,

table design http://pastebin.com/RW6vLAVP

And configuration:

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