Обсуждение: query creates a huge toast tables
Hi,
This query (postgis) didn't endup after 4 hours....and eat 40gig of disk space
SELECT id, gridcode, ST_Difference(a.geom32198_s,b.geom32198_s) as geom32198_s
into potentialite
FROM province as a, potentialite_tmp as b;
I stopped the execution and cancel request sent appears, but after an hour the request wasn't stopped yet.
So I killed the process and restat postgres.
The database is up and running but I didn't get the 40gig of disk space back. And only 5gig remains on the server
It is this table that is so huge
pg_toast.pg_toast_11037520
I tried vaccuumdb without success. Vacuumdb full didn't work because only 5 gig left on the server
What can I do to get the disk space back ?
Can I simply drop pg_toast.pg_toast_11037520?
I'm using
"PostgreSQL 9.1.3 on x86_64-suse-linux-gnu, compiled by gcc (SUSE Linux) 4.3.4 [gcc-4_3-branch revision 152973], 64-bit"
"POSTGIS="1.5.3" GEOS="3.3.2-CAPI-1.7.2" PROJ="Rel. 4.8.0, 6 March 2012" LIBXML="2.7.6" USE_STATS"
thanks in advance for your help

What table (if any) does it belong to? "select relname from pg_class where oid=11037520"

Hi Jeff
This query returns
"tmpcarteprotection4"
tmpcarteprotection4 is old and useless, it could be dropped. Before dropping it is there something else I should do?
Thank you very much for your help
