function Get-DbaDbUdf {
<#
    .SYNOPSIS
        Gets database User Defined Functions
 
    .DESCRIPTION
        Gets database User Defined Functions
 
    .PARAMETER SqlInstance
        The target SQL Server instance or instances
 
    .PARAMETER SqlCredential
        Allows you to login to SQL Server using alternative credentials
 
    .PARAMETER Database
        To get User Defined Functions from specific database(s)
 
    .PARAMETER ExcludeDatabase
        The database(s) to exclude - this list is auto populated from the server
 
    .PARAMETER ExcludeSystemUdf
        This switch removes all system objects from the UDF collection
 
    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Get-DbaDbUdf -SqlInstance Server1 -ExcludeSystemUdf
 
        Gets the User Defined Functions for all databases that are not system objects (there can be 100+ system User Defined Functions in each DB)
