Обсуждение: BUG #2301: xml2 library not running on the Win Pg 8.1
The following bug has been logged online: Bug reference: 2301 Logged by: Balázs Klein Email address: Balazs.Klein@axelero.hu PostgreSQL version: 8.1 Operating system: WinXP Description: xml2 library not running on the Win Pg 8.1 Details: I have raised this issue in the pgsql.general newsgroup, Subject: installing xml2 for pg 8.1 on winxp, but as I got no answers so far I am submitting this as a bug. 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. After placing the downloaded dll's to their places, 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.

Did you recompile pgxml against 8.1, or are you trying to use DLLs that were compiled against 8.0? The latter won't work. You need to either produce yourself or convince someone else to provide you with a DLL that was compiled against 8.1. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc.

Not included in the /contrib makefile) which requires additional libraries. It's on my list to look at, but I've not got to it yet. Regards, Dave.

Dear Alvaro, no, I didn't get a reply on pgsql.general - I am not complaining about it just wanted to pass the info to a place where it might be useful and explain why I am cross-posting. I didn't compile anything just downloaded the 8.1 Win binaries from http://www.postgresql.org/ftp/binary/v8.1.3/win32/ and the binaries from www.throwingbeans.org/pg801_windows_xml.zip they didn't work together, so I posted first to Tom Dyson thomasdyson@gmail.com and he said the problem is with the pg compile so I posted here as well in the hope that in a future version they may work together. Thanks for your reply.
