Postgres issues post 10.7.2

All,

I'm just about running out of ideas - I have a serious server error post 10.7.2 upgrade - which incidentially I had to reinstall as the first install left me with a server that couldn't even administer itself! I cannot run either the Calendar or Address Book services - I have done some hunting around and traced the issue back to postgres - as it does not appear to be running.

I now seem to have a corruption somewhere in the postgres configuration - trying to start the service using serveradmin results in CANNOT_START_SERVICE_TIMEOUT_ERROR. I have however been able to run the postgres launch command from the command line (having worked out all the switches it needs) and it results in a cannot find "server.crt" error message (no such file or directory). However, if I remove the -c log_statement=ddl from the command line it works without issue.

It is correct this file does not exist anywhere on the hard drive (find . -name server.crt from root returns nothing - it also returns nothing on a server that is working!)

I have hunted through configuration files for references to server.crt but can only find it mentioned in /private/etc/apache2/extras/httpd_ssl.conf (or similar named file) - this however is identical to a working server so seems unlikely to be the cause.

I have also tried running the wipeDB.sh script and this has made no difference

Could really do with some pointers
