function Find-DbaUserObject {
    <#
    .SYNOPSIS
        Searches SQL Server to find user-owned objects (i.e. not dbo or sa) or for any object owned by a specific user specified by the Pattern parameter.
 
    .DESCRIPTION
        Looks at the below list of objects to see if they are either owned by a user or a specific user (using the parameter -Pattern)
        Database Owner
        Agent Job Owner
        Used in Credential
        USed in Proxy
        SQL Agent Steps using a Proxy
        Endpoints
        Server Roles
        Database Schemas
        Database Roles
        Database Assembles
        Database Synonyms
 
    .PARAMETER SqlInstance
        The target SQL Server instance or instances. This can be a collection and receive pipeline input
 
    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
 
    .PARAMETER Pattern
        The regex pattern that the command will search for
 
    .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.
