Hi everyone,
I use PostgreSQL 8.1.9 and Debian 4.0 "etch" Linux kernel 2.6.18
(debian precompiled).
I install my db and insert one test database without problems.
I create schema of this db as sql script. Sql script is a list about
create relation table test_table.TEMP__N and set relation and drop
relation table where N about from 0 to 300.
When I insert sql script with shell command:
psql -d test < script.sql > script.log 2> script.err
in file error I see 3 error sort:
ERROR: could not extend relation 1663/63659/85595: No space left on device
ERROR: could not write block 21 of temporary file: No space left on device
ERROR: could not write to hash-join temporary file: No space left on device
I test all in two server machines:
1) AMD Opteron(tm) Processor 244, 1790.535MHz, 1024MB
2) AMD Opteron(tm) Bi Processor 244, 1804.153MHz, 8192MB
First errors begining when sql script inserts:
1) relation about TEMP__100
2) relation about TEMP__227
In any case there is space in device after sql script:
1)

/dev/md0 953M 254M 699M 27% /

Can someone help me?
Thanks very much for the help in advance.

Check your queries. I suspect you've written an incorrectly constrained
join that is producing many more rows than you expect.

Dear Tom,
I attach you the sql script and file.log and file.err obtain with command:
psql -d sgdlite < sgdlite_mart.sql > sgdlite_mart.log 2> sgdlite_mart.err
first server machine is:AMD Opteron(tm) Processor 244, 1790.535MHz, 1024MB
second server machine is:AMD Opteron(tm) Bi Processor 244, 1804.153MHz,
8192MB
I had "could not write to hash-join temporary file" one time with
second server machine.
Thanks for you help.
Regards,
Alessandra Bilardi
