Re: Problems displaying data from Query Tool and View/Edit Data Tool.

Hi Steve,

The main difference between those tools and the rest of the code is that
they execute their queries in a separate thread.

I wonder if PostgreSQL needs to be compiled with --enable-thread-safety
on Solaris for pgAdmin to work as it should?

Regards, Dave.
