Besides the column_info() update, the much reported "pg_server_version" bug is fixed. Rudy Lippan implemented the quote() function in C. In an un-scientific benchmark of my own, this is twice as fast as the original implementation, given enough values to work on. (Was it 20,000 in my test?).
There are also about 100 new tests I believe. The release was tested against Postgres 7.4, 7.3, 7.2, and 7.1, all passing at 100%.
Congratulations to all the DBD::Pg team and contributors!
