There is overhead transforming data to and from types that the Python interpreter can work with. How much overhead is rather subjective - we find it fast enough for the things we use it for. The Python syntax can become a bit cumbersome if you need to interact with the database a lot, in which case plpgSQL is likely the better language for that job. There are counter examples too, where the Python code is much cleaner and in some cases lets you do things impossible in plpgSQL. Access to the Python standard library gives you a great toolkit, and it being 'unsafe' you can do stuff you would otherwise need to write and deploy C extensions for. -- Stuart Bishop <stuart@xxxxxxxxxxxxxxxx> http://www.stuartbishop.net/ -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
