Title resource name PostgreSQL Database Adapter
Description resource summary psycopg is a PostgreSQL database adapter for the Python programming language (just like pygresql and popy.) It was written from scratch with the aim of being very small and fast, and stable as a rock. The main advantages of psycopg are that it supports the full Python DBAPI-2.0 and being thread safe at level 2. ZPsycopgDA is a Zope Database Adapter based on psycopg and included in the psycopg package. <p>psycopg is different from the other database adapter because it was designed for heavily multi-threaded applications that create and destroy lots of cursors and make a conspicuous number of concurrent INSERTs or UPDATEs. Every open Python connection keeps a pool of real (UNIX or TCP/IP) connections to the database. Every time a new cursor is created, a new connection does not need to be opened; instead one of the unused connections from the pool is used. That makes psycopg very fast in tipical client-server applications that create a servicing thread every time a client request arrives. <p>Please note that this is not the official homepage for psycopg and that new versions are uploaded to Zope's site as a convenience for ZpsycopgDA (psycopg database adapter for Zope) users. The official home page for psycopg is on <a href="http://initd.org/software/initd/psycopg">init.d</a> web site.

If you can read this text, it means you are not experiencing the Plone design at its best. Plone makes heavy use of CSS, which means it is accessible to any internet browser, but the design needs a standards-compliant browser to look like we intended it. Just so you know ;)
