[elephant-devel] Removing indexes from existing classes

2009-01-06 Thread Robert Synnott
Hi, Quick question. If I have existing instances of a class with index on slot X, and I wish to remove that index, is it sufficient simply to remove the index in the class definition, or do I need to do something else? Thanks Rob. ___ elephant-devel site

[elephant-devel] Postmodern backend; are values ever removed from the blob table

2008-12-10 Thread Robert Synnott

Is there anything I can do about it short

Hi, I'm wondering does anyone have any tips on setting up postgres as a postmodern backend for Elephant. I suspect that my issues are just a case of not really having enough memory for my data set, but if there's anything obvious I should be doing, I might as well do that first. Thanks Rob ___
