Re: Create extension tablefunc fails with "wrong ELF class: ELFCLASS32"

Thanks for the quick reply,

This could indeed be a solution since the webhosting migrated the old
folder I used for installation on 32bit.

I am not very familar with linux, I'd like to ask for two clarifications:

1. You refer to my installation of postgresql-9.1.3 ? as far as I
understand the tablefunc I am trying to load is included there
2. Would I need to "uninstall" postgresql-9.1.3 somehow before running the
install again?

Thanks,

Jan
