It is my hope that the following "patches" to libpgtcl get included
in the next release.

See the update to the README file to get a full description of the changes.
This version of libpgtcl is completely interpreter-safe, implements the
database connection handle as a channel (no events yet, but will make it
a lot easier to do fileevents on it in the future), and supports the SQL
"copy table to stdout" and "copy table from stdin" commands, with the
I/O being from and to the connection handle.  The connection and result
handles are formatted in a way to make access to the tables more efficient.
