Hi!

I am working have a year with PostgreSQL Windows Database.
I am very happy with the Database and its looks good.

I have to report of critical bug:
I am using functions (Store procedure) to update database.

When I passing for example 20 prams' to update a database its work fine.
But yesterday a saw when one of the parameters the value is – "109922:11"
I gut an error parameter 11 is empty – he thinks the value is a
parameter.
When a change this value to – "109922.11" the function works fine.

I working with the latest release 8.1.2 windows addition.
