I am running PostgreSQL 9.6.5 on x86_64-pc-mingw64, compiled by gcc.exe (Rev5, Built by MSYS2 project) 4.9.2, 64-bit on win2012 with 12Gb RAM The dumped table is 0.5TB, 17 million rows and LOB uses about 99% of the space. The pg_dump consumes the entire system memory and swap, then terminates with out of memory error Is it a bug or normal behavior? If I do not include LOB in the dump, it works fine. Here is the dump output: C:\Users\Administrator> pg_dump -h localhost -Fc -a -b -t signatures -v > d:\postgresql\sig.dmp pg_dump: last built-in OID is 16383 ... pg_dump: reading row security enabled for table "ibisl1.signatures" pg_dump: reading policies for table "ibisl1.signatures" pg_dump: reading large objects pg_dump: reading dependency data pg_dump: saving encoding = UTF8 pg_dump: saving standard_conforming_strings = on out of memory Jean-Marc Lessard |
