Subject: Re: 8.3rc1 Out of memory when performing update
A simple update query, over roughly 17 million rows, populating a
newly added column in a table, resulted in an out of memory error
when the process memory usage reached 2GB. Could this be due to a
poor choice of some configuration parameter, or is there a limit
on
how many rows I can update in a single statement?
I believe that it is plataform problem. Because on *nix this
limit
don't occur. But I don't specialist Windows.
On most Windows Servers(except for database edition and a few other
variants), 2Gb is the most you can address to a single
process without booting the machine with a special parameter called
\3G
which will allow for allocating up to 3Gb per process. That is the
limit unless you get special versions of windows server 2003 as far as
I
know. If you do a google search on \3G with windows you will find
what
I am refering too.
Windows 32 bit is limited to 2 or 3 GB as you state but 64 bit Windows
isn't. 32 bit Linux has similar limits too.
Well, PostgreSQL on Windows is a 32-bit binary, so the limit applies to
this case.
