Current JIRA setup specification:
JIRA version- 5.2.11
PostgresSQL Version - 9.0.3
Opertaing system - Microsoft Windows server 2003 R2 (64bit) SP2.
As per your Atlassian docs JIRA 5.2.11 supports Windows 2012 but whether it will support postgresSQL 9.0.3 ( PostgreSQL Official site is showing 9.0 as unsupported version).
Kindly suggest.
