Installation database config problem

I have been struggling with the installation of egroupware. It will not complete the setup, various elements give the error message:
|
| An error happened
|
| SQLSTATE[08006] [7] could not translate host name “port=5432” to address: Name or service not known
|

I have tried redoing the header admin setup and leaving the port number blank, since it is the default for postgresql, but this makes no difference.

I assume this is not a bug – but can anyone suggest which config file I should edit to avoid this problem?

TIA

Replying to my own post…

I’ve come to the conclusion this must be a bug in phpgwapi/inc/adodb/drivers/adodb-postgres64.inc.php

so I am going to try to reinstall with mysql instead – if I can work out how to do that.

With mysql instead of postgresql, there is no problem. It likely is a bug.
