Should you encounter IDB service refusing to start or notice the IDB service down and note in the PG_log (Omniback/Service/DB80/PG/PG_Log/) (var/opt/omni/DB80/PG/PG_log/)the following entry
...WARNING C-00000000005E4B20: hpdpidb/hpdpidb_app@127.0.0.1:50911 Pooler Error: pgbouncer cannot connect to server
...WARNING C-00000000005E4B20: hpdpidb/hpdpidb_app@127.0.0.1:50914 Pooler Error: pgbouncer cannot connect to server
it would be recommended to check the exclusions of the AntiVirus software
This must be excluded:
C:\Program Files\PostgreSQL\8.x\bin\pg_ctl.exe
C:\Program Files\PostgreSQL\8.x\bin\postgres.exe

Antivirus software
If you have any antivirus software installed, you must exclude the data directories that are to be used by PostgreSQL and must exclude postgresql.exe process. If that still does not help, it may be required to completely uninstall the antivirus software from the machine.
Antivirus software can interfere with PostgreSQL's operation, because PostgreSQL requires file access commands in Windows to behave exactly as documented by Microsoft, and many antivirus programs contain errors or accidental behavior changes that cause these commands to misbehave subtly. Most programs do not care because they access files in fairly simple ways. Because PostgreSQL is continuously reading from and writing to the same set of files from multiple processes, it tends to trigger programming and design mistakes in antivirus software, particularly problems related to concurrency. Such problems can cause random and unpredictable errors, or even data corruption.
Antivirus software is also likely to dramatically slow down PostgreSQL's operation. For that reason, you should at least exclude postgres.exe and the data directories so the scanner ignores them.
What Anti-Virus software is compatible?
The systems used to build the Windows installers all run either Sophos AV or AVG Free Edition, and those systems pass a full set of PostgreSQL regression tests running those programs. Microsoft Security Essentials is also known to work.
Specific issues have been reported with the nod32 antivirus product. If you are using this product, add "postmaster.exe" to the list of excluded processes (available under advanced options). This has been reported to fix the problem.
Specific issues have also been reported with McAfee and Panda anti-virus software and NetLimiter network monitoring software. While some people do have PostgreSQL working with these software packages, there is no specific or even recommend solutions that have not worked in some cases, so the issues would appear to be installation specific, sometimes even requiring uninstallation.
Software firewalls
If you have any 3rd-party firewall software installed on your machine, try either disabling it or uninstalling it. There's really no need for 3rd party firewalls on Windows XP and above, as the built-in firewall provided by Microsoft does an excellent job already. Some badly-written 3rd party firewalls do not uninstall correctly, so after uninstallation you might have to tell Windows to repair its network settings.
If you had a 3rd-party firewall and have now uninstalled it, make sure to turn Windows Firewall back on, as many products turn it off during installation and fail to turn it back on during uninstallation.
