Hi...
I have a view across 3 tables, total some 5m rows.
I can extract parts of the view, entire rows, with a where clause
(eg: select * from view where cell_id=100000;)
If I try to select the entire view (eg: select * from view;) it runs for a while then gives the error msg "Killed" and
returnsto the system prompt, having exited psql.
The log says:
2009-08-10 00:19:01 NZST ben200601 woodb LOG: could not send data to client: Broken pipe
2009-08-10 00:19:48 NZST ben200601 woodb LOG: unexpected EOF on client connection
I have written a script along the lines of:
get distinct cell_id from table; > file
while read cell ; do
psql -d db -c "select * from view where cell=$cell;" >> output
done < file
This worked, & the number of lines in the output file is the same number as that returned by "select count(*) from
view;"(which works fine), but I'd like to find out the cause of the error. I assume there is some sort of timeout or
overflowoccurring, but I can't see any indication of what settings I can change to fix this. All the underlying tables
havejust had vacuum analyse run on them.
I'm running PostgreSQL 8.1.4 on x86_64 Linux, I know it is dated, but I'm not in a position to upgrade at this point.
Thanks,
