[pgadmin-support] VACUUM FULL Error

Hi pgAdmin support,

Recently truncated tables in Postgre SQL DB and now unable to free up disk space on server with the VACUUM FULL command.

The DB is 1.91TBytes in size.

Server is running Win 2008 R2 Standard Operating System.

Postgre SQL is version 8.1

Error message reads as follows:

ERROR:  out of memory

DETAIL:  Failed on request of size 134217728.

Adding memory to server does not seem to make any difference. Re-starting the server makes no difference. The VACUUM command always ends in the same record 134217728.

Is there any way to selectively VACUUM tables – divide and conquer approach.

Thank you in advance for any support you can provide
