The following bug has been logged online: Bug reference: 4004 Logged by: Manos Tsagias Email address: [EMAIL PROTECTED] PostgreSQL version: 8.3.0 Operating system: Mac OS X Description: out of memory Details:
hi, I used COPY to import a 2GB CSV file into a table. After almost 2 hours I got: ********* Error ********** ERROR: out of memory SQL state: 53200 Detail: Failed on request of size 32. Context: COPY mkil_ratings, line 92876876: "16452,1409665,4,2005-07-10" Before that, Postgresql was complaining about: HINT: Consider increasing the configuration parameter "checkpoint_segments". LOG: checkpoints are occurring too frequently (14 seconds apart) The above two lines were repeated many-many times and finally, the trace of the error: x 127.0.0.1(49853) COPY(728) malloc: *** error: can't allocate region x 127.0.0.1(49853) COPY(728) malloc: *** set a breakpoint in szone_error to debug TopMemoryContext: 34608 total in 4 blocks;
