Hi, My current database version is "PostgreSQL 9.1.11 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-3), 64-bit". I am trying to use function xpath in my query and got following error. "ERROR: function xpath(unknown, text) does not exist at character 8 HINT: No function matches the given name and argument types. You might need to add explicit type casts. I could see the library pgxml.so libray in /usr/pgsql-9.1/lib . Could someone please advise me what more needs to be done in order to run xpath queris? Thanks in advance. -- View this message in context: http://postgresql.1045698.n5.nabble.com/xpath-functionerror-tp5793724.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
