BUILD, INSTALL and INSTALL-CHECK
I was able to build the package and successfully ran MADlib
install-check against PostgreSQL 9.6.2.
Issue: There is no obvious reference to the PostgreSQL libxml
dependency in dev documentation. The madpack install-check
has failures (see below) if "--with-libxml" configure
option is not specified for PostgreSQL.
install-check errors encountered due to PostgreSQL
configuration without "--with-libxml" option:
psql:/tmp/madlib.0UIPlZ/pmml/test/table_to_pmml.sql_in.tmp:73: ERROR:
unsupported XML feature
DETAIL: This functionality requires the server to be built with
libxml support.
HINT: You need to rebuild PostgreSQL using --with-libxml.
CONTEXT: while creating return value
PL/Python function "pmml"
{code}
Story
As a MADlib installer, I want IC tests that use lib-xml to be skipped, so that
my install is clean and I do not have to wonder if there is a problem.
More: if at PMML export is called that requires lib-xml, then it will fail
with a run-time db error which is fine. This is not a commonly used function.
Acceptance:
1) madpack install succeeds and IC passes even tho PG does not have libxml
installed
