This information is to build postgresql 9.1.X on a Redhat6 machine.  postgresql9.1 will not officially be in a distro until Redhat7 and SLES 12, so for PCM to use it we need to build for the current Redhat6.3 which we will release xCAT/PCM produce.

[RHEL6]
1) Need to install rpmbuild from the distro and gcc on your build machine
2) Must have uuid-devel, did  not see to be in the Redhat6.3 distro.  
   * Downloaded the packages from 
     http://pkgs.org/centos-6-rhel-6/centos-rhel-x86_64/uuid-devel-1.6.1-10.el6.x86_64.rpm/download/
   * On x86_64, there's already an existed prebuilt rpm package available
     rpm -ivh uuid-devel-1.6.1-10.el6.x86_64.rpm
   * On ppc64, need to download the source rpm and rebuild it with the spec provided by xCAT.
     rpm -ivh uuid-1.6.1-10.el6.src.rpm
     cd /root/rpmbuild/SPECS
     backup uuid.spec to uuid.spec.orig
     cp uuid.spec provided by xCAT  in this directory to /root/rpmbuild/SPECS
     rpmbuild -ba /root/rpmbuild/SPECS/uuid.spec
     rpm -ivh /root/rpmbuild/RPMS/ppc64/uuid-devel-1.6.1-10.el6.ppc64.rpm

3) Use the below website to download src rpms for postgresql91.  I picked the latest
PTF level 9.1.5.
http://yum.postgresql.org/srpms/9.1/redhat/rhel-6-x86_64/
From here I got postgresql91-9.1.5-1PGDG.rhel6.src.rpm

4) Run rpm -ivh postgresql91-9.1.5-1PGDG.rhel6.src.rpm to install the source rpms on the build machine. 


5) When you installed the source rpm, it put the data in /root/rpmbuild
cd /root/rpmbuild/SPECS
cp postgresql-9.1.spec postgresql-9.1.spec.orig
We have modified the spec that Fedora16 used to build postgresql91, so 
that all the commands and code will go in the normal locations and provide 
that spec here
cp postgresql-9.1.spec provided by xCAT  in this directory to /root/rpmbuild/SPECS 

6) build  the rpms
rpmbuild -ba postgresql-9.1.spec

7) Packages required by PCM on RHEL:
   - postgresql, postgresql-libs, postgresql-server, postgresql-contrib

[SLES11]
1) Need to install rpmbuild from the distro and gcc on your build machine, and we need SLES11 SP2 SDK1 iso to install extra build dependencies
2) Must have uuid-devel, we can get it from "server:database:postgresql" project on OBS (OpenSUSE Build Service)
   * Download the packages from repository for SLE_11_SP2_Update
     - libossp-uuid16-1.6.2-36.1
     - libossp-uuid_dce16-1.6.2-36.1
     - libossp-uuid++16-1.6.2-36.1
     - uuid-devel
   * Or just add the repository
     zypper ar  http://download.opensuse.org/repositories/server:/database:/postgresql/SLE_11_SP2_Update/  postgresql_build
     zypper install uuid-devel

3) Download the src rpms for postgresql from "openSUSE" project on OBS
   * wget http://download.opensuse.org/repositories/openSUSE:/12.2:/Update/standard/src/postgresql-libs-9.1.5-7.8.1.src.rpm
   * wget http://download.opensuse.org/repositories/openSUSE:/12.2:/Update/standard/src/postgresql-9.1.5-7.8.1.src.rpm

4) Run rpm -ivh postgresql-9.1.5-7.8.1.src.rpm/postgresql-libs-9.1.5-7.8.1.src.rpm to install the source rpms on the build machine

5) When you installed the source rpm, it put the data in /usr/src/packages
cd /usr/src/packages/SPECS
cp postgresql.spec postgresql.spec.orig
We have modified the spec that OpenSUSE12.2 used to build postgresql to disable regression test.
cp postgresql-9.1.spec.sles provided by xCAT  in this directory to /usr/src/packages/SPECS

6) build  the rpms
rpmbuild -ba postgresql-libs.spec
rpmbuild -ba postgresql-9.1.spec.sles

7) Packages required by PCM on SLES:
   - postgresql, postgresql-libs, postgresql-server, postgresql-contrib
   - libossp-uuid16


Note: If not building 9.1.5-x then modifiy postgresql-9.1.spec and change the VERSION:   and RELEASE: line to match your level of postgresql.
