function Get-DbaDbTrigger {
    <#
    .SYNOPSIS
        Get all existing database triggers on one or more SQL instances.
 
    .DESCRIPTION
        Get all existing database triggers on one or more SQL instances.
 
    .PARAMETER SqlInstance
        The target SQL Server instance or instances.
 
    .PARAMETER SqlCredential
        SqlCredential object used to connect to the SQL Server as a different user.
 
    .PARAMETER Database
        The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed.
 
    .PARAMETER ExcludeDatabase
        The database(s) to exclude - this list is auto-populated from the server
 
    .PARAMETER InputObject
        Allow pipedline input from Get-DbaDatabase
 
    .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/ca
