Hi Francisco,

Thanks for the response.

Well its in my web app so I don't have an easy way to run it from the
command line.

Yes thats why it seems like a Mono issue.

I don't think so. I'm using a VM under VMWare and installed pgsql from
Yast. The machine was upgraded from open sues 10.2 to 10.3 but after
the initial upgrade it was working fine and only recently after
updating Mono from svn this error started appearing. The file that it
says it can't load does exist and as I say runnig the same web code on
windows and using the very same pgsql database on the vm there is no
error at all.

could not load library "/usr/lib/postgresql/plpgsql.so":
/usr/lib/postgresql/plpgsql.so: undefined symbol: get_func_arg_info
