Hi,
I am trying to restore a table out of a dump, and I get an 'out of
memory' error.
The table I want to restore is 5GB big.
Here is the exact message :
admaxg@goules:/home/backup-sas$ pg_restore -F c -a -d axabas -t cabmnt
axabas.dmp
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 5492; 0 43701 TABLE
DATA cabmnt axabas
pg_restore: [archiver (db)] COPY failed: ERROR: out of memory
DETAIL: Failed on request of size 40.
CONTEXT: COPY cabmnt, line 9038995: "FHSJ CPTGEN RE
200806_004 6.842725E7 6.842725E7 \N 7321100 1101
\N
00016 \N \N \N \N \N \N -1278.620..."
WARNING: errors ignored on restore: 1
Looking at the os level, the process is effectively eating all memory
(incl. swap), that is around 24 GB...
So, here is my question : is pg_restore supposed to eat all memory ? and
is there something I can do to prevent that ?
Thanks,
Franck
