Обсуждение: Database Loading
Hello, I have to load a very large database. Is there a command that can load data in bulk faster than the copy command does? Carol Walter

I went to the page. It said the OS is Linux. Is there anything for Solaris. I've got Solaris 10.

It looks like it's just some C code, a shell file, and some sql scripts. It should compile and run fine on any postgresql supported platform (the operative word being "should"). They probably just listed Linux as the OS as it's likely the primary OS on which they wrote and tested it. Peter
Hi, Le mardi 19 février 2008, Carol Walter a écrit : > I have to load a very large database. Is there a command that can > load data in bulk faster than the copy command does? The next version of pgloader has been asked to implement some new parallel loading of a single file, which could speed up things by having several backends importing data at once. The implementation of this is now done and ready to get some tests, but still at a beta or release candidate status. If you want to try it (and report about your tests?), here's the current version of it: http://pgloader.projects.postgresql.org/dev/ http://pgloader.projects.postgresql.org/dev/pgloader.1.html#_parallel_loading Regards, -- dim
