They also support COPY now.

The driver beats libpq in speed by about 62%.
The memory consumption is on demand, by row, and not the whole result set.
Transport to and from the query is in binary and dynamically determined
per datatype, no quoting necessary.

Anyone interested in taking a peek at the (GPL copyright) driver, I
temporarily put up a small package which contains the working driver
in Pike at:

http://admin.cuci.nl/psgsql.pike.tar.gz

Pike is a C/C++/Java like interpreted language.
The production driver uses a PGsql assist class which is written in C to
accelerate (amazingly) few core functions (not included, but the driver
works fully without the PGsql assist class).
