Hi all

I was asked by application dev to rebuild PostgreSQL with libxml because
they get the following error from the server.

WITH x(col) AS (SELECT '<?xml version="1.0"
?><response><status>ERROR_MISSING_DATA</status></response>'::xml)

SELECT xpath('./status/text()', col) AS status

FROM x;

LINE 1: WITH x(col) AS (SELECT '<?xml version="1.0" ?><response><sta...

^

DETAIL: This functionality requires the server to be built with libxml
support.

HINT: You need to rebuild PostgreSQL using --with-libxml.

I then did the following:

1. We installed library 'xml2' (version >= 2.6.23)

2. ./configure --with-libxml

3. gmake

4. gmake install

I did not touch the database. They‘re getting the same error. Please advise
if there was something else I needed to do.

Thanks

-I am not sure because it’s setup I was not involved in

what OS/distribution is this on?

- it’s running on CentOS release 6.4 (Final)

Another example:

c9900=# begin ;

BEGIN

c9900=# create table kmgtest (col1 xml);

CREATE TABLE

c9900=# insert into kmgtest values ('<one>something</one>');

ERROR: unsupported XML feature

LINE 1: insert into kmgtest values ('<one>something</one>');

Check your config.log to make sure it actually found libxml.

Depending on how you installed it, it might not be found by configure
without an explicit path - a --with-libxml=/path/to/libxml/install/dir

Why aren't you using operating system packages? And why 9.2.4?

Was the database server restarted after the new version was built?

It was not restarted - Should I do so?

Yes, otherwise the old binary will still be running.

Do also take note of Craig Ringer's email on this thread; in
particular you should always run the latest minor version, which
is currently 9.2.8.

Thanks very much, I restarted the database and the problem was fixed. We
will look into using the versions as suggested below

why aren't you running the version in the pgdg yum repository, which
includes XML support and a lot more.
