The term "The PostgreSQL™ JDBC driver" refers to the project as a
whole. Obviously certain classes and methods *may* be (inherently)
thread-safe, but "The PostgreSQL™ JDBC driver" project is not
developed for a multi-threaded use, and the majority of the
functionality (Connections, Statements, Result Sets, etc.) can *only*
be used by a single thread.
