Mario,
You reported three problems:
1. Parameter limitation due to the use of single char (entered as bug #907)
2. Default connection string cannot have ending colon (entered as bug #908)
3. Unreferenced symbols when using PostgreSQL 7.4.3
Since I know that you compiled from CVS HEAD earlier, I though I'd
inform you that I've delivered fixes to all your issues. Please let me
know if you run into any other problems.
Regards,
Thomas Hallgren
