Обсуждение: What are the minimal files required to backup a postgresql database
I need to package the ability to backup a PostgreSQL database in my application? I obviously need to add pg_dump.exe to the package, and the dlls required are listed below, 15/08/2007 15:41 12,288 comerr32.dll 15/08/2007 15:41 139,264 gssapi32.dll 15/08/2007 15:41 19,968 k5sprt32.dll 15/08/2007 15:41 602,112 krb5_32.dll 27/02/2007 15:39 1,040,384 libeay32.dll 31/01/2003 19:41 916,849 libiconv-2.dll 16/03/2004 16:37 898,048 libiconv2.dll 27/04/2004 10:45 32,256 libintl-2.dll 06/05/2005 17:52 103,424 libintl3.dll 31/10/2008 07:15 167,936 libpq.dll 05/11/2005 14:51 169,092 libpq81.dll 16/10/2007 13:40 348,160 msvcr71.dll 02/12/2006 00:03 626,688 msvcr80.dll 09/03/2010 16:09 520,190 sqlite3.dll 27/02/2007 15:40 196,608 ssleay32.dll Are there any other executables besides pg_dump I need to add to this list? If some of them are likely to come in useful, rather than necessary for backup I don't mind adding them Regards /voipfc

There's some documentation about that in the postgreswiki IIRC, look for debugging tools on windows. I don't think you'd need all of these, but I can only guess. Here are my thoughts though: > 15/08/2007 15:41 12,288 comerr32.dll No idea what this is. > 15/08/2007 15:41 139,264 gssapi32.dll > 15/08/2007 15:41 19,968 k5sprt32.dll > 15/08/2007 15:41 602,112 krb5_32.dll I think you only need these if you're using kerberos or GSSAPI for authentication. > 27/02/2007 15:39 1,040,384 libeay32.dll No idea about this one. > 31/01/2003 19:41 916,849 libiconv-2.dll > 16/03/2004 16:37 898,048 libiconv2.dll These are most likely two versions of the same dll. Taking the newest should be safe. > 27/04/2004 10:45 32,256 libintl-2.dll > 06/05/2005 17:52 103,424 libintl3.dll Same here. > 31/10/2008 07:15 167,936 libpq.dll > 05/11/2005 14:51 169,092 libpq81.dll And same here; the libpq81.dll is probably left over from an old PG81 installation. > 16/10/2007 13:40 348,160 msvcr71.dll > 02/12/2006 00:03 626,688 msvcr80.dll It needs two different runtimes? Maybe they're disjunct then? > 09/03/2010 16:09 520,190 sqlite3.dll No idea why you'd want SQLite in there, I can't imagine it being used by pg_dump. > 27/02/2007 15:40 196,608 ssleay32.dll Something to do with SSL apparently; you should only need that if you plan to use pg_dump over SSL. > > Are there any other executables besides pg_dump I need to add to this list? > > If some of them are likely to come in useful, rather than necessary > for backup I don't mind adding them That highly depends on what you're trying to accomplish. I'd think pg_dumpall, pg_restore and psql would be useful too. Alban Hertroys -- Screwing up is an excellent way to attach something to the ceiling. !DSPAM:737,4c162b52286211582820103!

There's some documentation about that in thepostgres wiki IIRC, look for debugging tools on windows. depends.exe from dependencywalker.com . Basically, ship everything in the `bin' directory where pg_dump lives if it's listed by depends.exe as used by pg_dump. Also make sure to provide and silent-install the MSVC++ 2005 redist, which you can get from Microsoft. Do *NOT* ship any system DLLs. > Something to do with SSL apparently; you should only need that if you plan to use pg_dump over SSL. That depends entirely on how DLL linkage is done. If it's an immediate dependency rather than a delayed dependency, which it will be unless configured otherwise, pg_dump will fail to load without that DLL even if it's not going to use ssl. I'm not on a Windows box with PG at the moment so I can't test. -- Craig Ringer
