Обсуждение: plpython array support
Just a simple question--does plpythonu (8.3beta) have support for arrays? I don't see a specific mention of it in the docs, so I suppose not. Thanks, Sean

I've been using them since 8.1, for sure, but I think that on 7.4 I already had code with arrays inside the database... -- Jorge Godoy <jgodoy@gmail.com>

I know that postgresql supports arrays, but I still don't see how plpython supports arrays. I noticed this post: http://archives.postgresql.org/pgsql-general/2007-01/msg01417.php from January, 2007 that suggests how to use the string representation of an array to convert to/from python arrays. This will work, but I was wondering if there is now a true conversion from postgresql arrays to python and vice-versa. Thanks, Sean

Beyond the simple number and string times everything gets cast to a string (arrays, tsvectors, etc.). I have no idea if anyone is working on this for 8.3 or later. -- Stuart Bishop <stuart@stuartbishop.net> http://www.stuartbishop.net/
