VACUUM ANALYZE problem on linux

Hello!
  A week ago I reported a problem with VACUUM ANALYZE on linux and memory
error. Three good guys saw my database and two of them for VACUUM problem,
I hope (Tom Lane and Thomas Lockhart).  Have you reproduced the case?
  I ran VACUUM ANALYZE on table basis. Results:

----- Script -----
VACUUM ANALYZE sections;
VACUUM ANALYZE subsections;
VACUUM ANALYZE positions;
VACUUM ANALYZE cities;
VACUUM ANALYZE districts;
VACUUM ANALYZE shop_types;
VACUUM ANALYZE shops;
VACUUM ANALYZE producers;
VACUUM ANALYZE products;
VACUUM ANALYZE correspondents;
VACUUM ANALYZE shop_corr;
VACUUM ANALYZE money4corr;
VACUUM ANALYZE raw_maillog;
VACUUM ANALYZE corr_mail_errors;
VACUUM ANALYZE pos_rating;
VACUUM ANALYZE motd;
VACUUM ANALYZE central;
VACUUM ANALYZE bad_data;
VACUUM ANALYZE today_history;
VACUUM ANALYZE currencies;
VACUUM ANALYZE currency_exch;
VACUUM ANALYZE param_int;
VACUUM ANALYZE param_str;
VACUUM ANALYZE param_float;
VACUUM ANALYZE param_datetime;
VACUUM ANALYZE palette;
VACUUM ANALYZE units;
VACUUM ANALYZE mail_ecod;

pqReadData() -- backend closed the channel unexpectedly.This probably means the backend terminated abnormally before or
whileprocessing the request.
 
We have lost the connection to the backend, so further processing is impossible.  Terminating.

  If I remove "products" from script, the next table to fail is "palette". If
I remove "palette" - all goes well.
