I hope I am reporting this in the right forum, if not please tell me so and next time I'll be better. There might be a problem with a missing extension in the pre-compiled windows version of Postgres 8.1 It looks as though it's the 'MemoryContextSwitchTo' library which is present in 8.0 but missing from 8.1. I was trying to install the xml2 library to Postgres as I found it on http://www.throwingbeans.org/postgresql_and_xml_updated.html but I had no luck. So I contacted Tom Dyson the author of the package and he informed me that there were others having a similar problem with the 8.1 compile while the library worked fine in the 8.0.3 version and he suggested that based on e-mails he got the problem might be the one I mentioned above. I just offered to report this problem of the build, unfortunately I can't help much more as this is far too high level for me. The actual error I get is: When I run CREATE OR REPLACE FUNCTION xml_valid(text) RETURNS bool AS 'libpgxml' LANGUAGE 'c' WITH (isStrict); I got the error message ERROR: could not load library "C:/Program Files/PostgreSQL/8.1/lib/libpgxml.dll": The specified procedure could not be found. Thanks for the help. Balázs
